Sealant Moment: varieties, features, tips for use

The need for tightness can be found not only in the production sector, but also in domestic conditions. The popularity of sealing with Moment silicone sealant is determined by the aesthetic appearance and reliability of the joints. There are quite a lot of sealing compounds in our time, but the Moment sealants are considered the most popular.

Features

Universal “Moment” is a popular sealant, which consists of many components.

And these are such substances:

polymer silicone
thixotropic silica additive,
the composition of this sealant includes acetoxysilane,
antifungal component.

In the markets today you can find a variety of adhesives of the brand brand “Moment”. And also this company produces assembly foam and self-adhesive tape.

The main features of Moment sealants are:

plasticity of the material after solidification,
increased rate of adhesion to the processed material,
resistance to temperature changes and resistance to mechanical stress,
not affected by moisture
long term use of the surface after treatment with the composition,
low cost
resistance to external influences,
and even the sealant meets all hygienic requirements and environmental standards.

It is difficult to overestimate the advantages that a high-temperature sealant has, it has a short drying period, it is colorless, which makes it possible to use it even for mirrors. Specifications make it possible to use heat-resistant material in the bathroom.

It has a “Moment” and drawbacks, but they mainly relate to the surface treatment itself, which is not prepared for the job.

Types and characteristics

All sealants today are divided into only 2 main types:

One component composition. This type is sold in any hardware store and is one of the most common. Compounds of this type are sold in tubes of metal or polyethylene. This component hardens due to the presence of moisture in the air. The main disadvantage of this type is rapid hardening, but only if the surface is treated with a thin layer. And if the layer is more than 1.2 cm, then the sealant hardens for a long time.
Two-component type. Such mixtures are frozen in any layer, but the cost of such a composition is higher, since they are mainly used for industrial purposes.

Sealants "Moment" are one-component types, as they are intended for use in domestic purposes.

The manufacturer “Moment” manufactures two types of sealants. The first type is silicone based sealants, and the second type is based on acrylic water dispersion.

Acrylic-based sealants are more resistant to frost and to various adhesions of the treated surfaces. The main disadvantage of acrylic compositions is the inability to use in an environment with constant moisture. As for the color of such a sealant, it is mostly white.

Silicone sealant is made on the basis of rubber polymer. This component makes the mixture more elastic and makes it possible to harden in a short time, even at room temperature. Due to this characteristic, Moment silicone sealants are sold in special plastic tubes, which retain its liquid and plastic state for some time after manufacture. Tubes can be produced in volumes from 85 ml to 250 ml.

If you separate the compositions, starting from the scope of use, then they are construction, automotive and special.

In composition, they are divided into two types:

Neutral Instead of acetic acid, alcohol is added to the composition of such a material, and thus a less acrid smell is obtained. They can be used outdoors and indoors. Such mixtures are used in the field of shipbuilding, for sealing freezers, they can be transparent and white.
Universal sealants. The manufacture of this composition takes place with the addition of vinegar mixture, which gives an unpleasant and pungent odor, and when interacting with non-ferrous metal, cement and similar materials, which include alkali, it causes corrosion. This type of sealant is made in white or transparent color. It can be used for internal processing, that is, indoors, and for outdoor work, as it is moisture and heat resistant. The cost of such a composition is lower than neutral.

The company "Moment" produces a sealant that has a silicone base, but at the same time provides a triple protection against corrosion, mold and mildew on the reverse surface. The warranty period for such protection is about 5 years. If it has not frozen yet, then it can be easily removed with a sponge.

Henkel also produces sealant "The moment of Herment", It can be used for both domestic and professional use. Such a sealant is divided into several types:

Premium white, which is highly resistant to moisture, and consists of silicone. This kind can be called the most heat-resistant.
The next type, which is made on the basis of silicone and sodium silicate, copes with oil, gasoline, high temperature, which can reach 300 degrees. It dries quite quickly, and its color may even be red.
The type of sealant Sanitary is used for the glazing of shower stalls and bathtubs, but it cannot be used for processing stone and rusty surfaces; its curing speed is about 15 minutes.
Aquarium view, used for processing painted and glass surfaces that lend themselves to frequent vibrations. It is popular because it has a high level of moisture resistance, and the color of this composition is exceptionally transparent.

The same series of Moment materials includes a gray sealant, which is made on the basis of polyurethane. It is often used as a grout for moving joints and as an adhesive for tiles. It is resistant to moisture, acids, alkalis, water and similar negative factors. But it has a drawback, because under direct sunlight it burns out and for some time loses its elasticity.

Consumption

Any Moment sealant can be used for surface treatment at temperatures not lower than + 6 degrees and not higher than + 40 degrees. It must be applied on a previously prepared surface that is cleaned of rust, dirt, oil, dust and similar elements. Although such sealants do not have adhesion, it is better to degrease the surface for better adhesion. The seam layer must be at least 5 mm and not more than 1.2 cm.

The consumption of silicone sealant depends on the depth of the gap and the thickness of the layer. In order to find out the consumption of material, you can use online calculators on any construction site. And also on each package it is indicated on what area there will be enough funds from one package. For example, if you have a joint of 6 mm wide and 3 mm deep, with these parameters you will need an average of 20 ml of silicone sealant per 1 meter of joint.

If you applied a layer of sealant on the surface, but not as it should, then you need to wipe it with a dry sponge or rag, but before it begins to harden and harden. If it hardens, then it can only be removed mechanically. In the event that the sealant accidentally gets into your hands or in an unnecessary place, then it must be removed with a solvent.

Tips

The main criterion for the correct choice of sealant is a comparison of different manufacturers by the property of the composition and preliminary determination of the scope of its application. But experts advise starting from some more criteria:

From the presence or absence of a coloring substance in the sealant. If there is no dye in the sealant, then after full hardening it becomes transparent. This type of sealant can be used as an adhesive.
Sealant packaging volume. If you need to process windows, then it is actual and better to purchase a sealant with a capacity of 85 ml, this volume is enough to process 1 window, and if you have more windows, then it is more advisable to purchase a sealant with a packing of 280 ml than buy 4 small packages. Thus, you significantly save finances.

Since Henkel improves its products every year, the Moment brand has become popular not only in our country, but throughout the world. The sealant of this brand has reliability, high quality and durability. And also such products have a very reasonable cost.

But on the recommendation of specialists, you should not save and neglect your health, and it is better to choose a neutral type of Moment sealants, which include alcohol instead of acetic acid. Such a composition, of course, is more expensive, but it is better not to save on safety.

During the execution of work, it is necessary to ventilate the room, as well as observe the other safety measures.

Bituminous

Sealant Moment has increased moisture resistance and heat resistance properties, as well as good adhesion. It is more suitable for sealing joints of sewer pipes, working with drainage systems, as well as updating roofs and roofs. Sealants Moment can be effectively used in construction works, and not only thorough, but also finishing, both outside the premises and inside.

Aquarium

Unlike other varieties, it is an ecological composition without chemical impurities, which makes it absolutely safe for animals, fish and people. Suitable for gluing joints and cracks in aquariums, sealing showers, dries very quickly, has a high resistance to moisture.

Sanitary

Another distinctive type of sealant, in the composition of which you can find impurities of antifungal and antibacterial substances. Ideal for various rooms with high humidity, for work in public places, in order to prevent the development of pathogenic bacteria.

Belongs to the category of premium materials Moment. The composition has a rich variety of components, is characterized by high heat resistance. Unlike analogues, it is able to withstand the highest temperatures up to +300 ° C and even frost up to -50. Most often, the variety is used for industrial purposes, for sealing joints and processing wires of electrical appliances, furnaces, chimneys, shields and motors.

Scope of application

Sealant Moment with universal technical characteristics has found its application in various fields, and is also suitable for domestic use. Depending on the selected composition, the type of sealant will determine its scope of use. For example, a silicone-based compound, Premium 300ml or “Moment Germent silicone”, can be used to seal cracks and seams on the glass of shower cabins, in baths, saunas, pools. An additional function of the adhesive composition is that it prevents the likelihood of the appearance and spread of the most common problems for rooms with high humidity - fungus, mold and various bacteria.

The most common areas of application of the compounds:

Ensuring water and air tightness of the seams of windows, glass surfaces and products, to ensure tightness.
When mounting mirrors.
To increase the durability and service life of tiles, when laying and carrying out repair work with it.
For grouting, after finishing the room with vinyl.
Preparation of various materials and surfaces for further technical processing.
Sealing joints and seams of sewer and other pipes.
Alternative adhesives for mounting plumbing to the wall.
Ensuring thermal insulation of facades of residential and non-residential buildings, premises - silicone-based sealant is suitable.

Packaging

Sold one-component sealants for home use in special tubes, ready for use.

In combination with the single-component Moment compositions, there are clamps for the cap that provide reusable use of the tube without drying the substance inside them.

On the packaging of universal sealant you can find a special marking indicating that the substance is not painted.

Storage

In order for Moment sealant to provide a really good adhesion to the surface and last for a very long time, it is necessary to make sure that its expiration date has not gone out. You can store the composition in a closed form, until the expiration date indicated on the packaging in a dry place, without direct sunlight. Keep away from fire.

What is silicone sealant?

Previously, various putties were used to eliminate seams, seal holes, crevices, and other similar jobs. They had only a temporary effect, quickly washed off, lost aesthetic qualities, and the final result immediately after their application was not very pleasing. Today, silicone sealant is used for all these purposes. It allows you to create a durable, waterproof layer that lasts for many years, does not collapse, looks beautiful or even imperceptibly. Important! Silicone sealant is a material for creating a durable, waterproof layer, insulating joints, gluing surfaces and sealing joints, which has good resistance to external influences

Silicone sealants - specifications

It may seem strange, but elastic and soft silicone building sealant is made from the strongest material - silicon, which occurs in the form of quartz or sand. Polymers that are part of silicone are made from it.

Based on this, there are a number of advantages, among which:

the ability to stretch, which allows the use of silicone sealant on movable connecting sections,
high degree of strength
excellent indicator of adhesion - seals joints between elements made of ceramics, glass, wood, concrete, metal, plastic,
resistance to ultraviolet radiation and aggressive detergent components,
heat-resistant silicone sealant - retains its protective characteristics in a large temperature range (from -50 ° to + 300 ° C),
resistance to natural factors, allowing the use of sealant, both indoors and outdoors,
Does not respond to mold and bacteria.

Types of silicone sealants by component composition

The component composition of silicone sealants is quite complex. In the manufacture of it add the following substances:

silicone plasticizer - makes the material flexible,
vulcanizing agent, giving the material viscosity
silicone rubber (base),
adhesion primer - provides tenacity of the material with the surface,
amplifier - provides strength,
color filler.

All silicone sealants are divided into 2 main groups:

single-component - often used in construction and repair,
two-component - are used in the industrial field.

In turn, one-component silicone sealants, depending on the main component, are:

Alkaline Such sealants are included in the special purpose group, and the main component are amines.
Acidic. They are marked with the symbol “A” and belong to the group of universal silicone sealants with a low cost. In the manufacture, acetic acid is taken as the basis, the smell of which can be felt when the mass hardens.The disadvantage of acidic silicone sealant is incompatibility with most color grades, as it causes an accelerated corrosion process. They are also not recommended for use with marble elements and with cement material containing alkaline particles.
Neutral Ideally neutral silicone sealant is combined with surfaces made of any materials due to the component composition, which is based on ketoxime or alcohol.

When choosing a particular type of sealant, pay attention to the special additives used in the manufacture. There are 4 main types of additives:

Dyes. Colored pigments are added to the composition during manufacture, therefore, after drying, the material does not stain.
Mechanical fillers. Provide excellent tenacity to the silicone mass with the treated surface.

Important! Mechanical additives include silica dust or chalk.

Important! If you take into account the nature of the additive, you can significantly expand the scope of the sealant. Watch an interesting video review of silicone sealants to quickly understand which one you need.

Stamps and remarks: which manufacturer to trust

When choosing and buying silicone sealant, you should adhere to the rule: a quality product can not be cheap. As mentioned above, unscrupulous manufacturers are cunning, offer a low price due to the same low quality. Of course, verified brands also have defective lots, but their share is extremely small.

Basically, low quality is provided initially - a large percentage of impurities proportionally worsens the quality of silicone: elasticity and strength are reduced, resistance to aggressive influences is reduced, color changes, and curability is broken.

When choosing a quality product, you need to pay attention to the following factors:

Manufacturer - there are quite a few verified brands: Macroflex, Sudal, Moment, Econ, Quadro.
Original branded packaging with all the information (quality indicators and composition).
The seller has certified copies of the certificates.

It should be wary of the product:

With a large weight (more than 340 grams with a volume of 310 ml).
With the inscriptions "100% silicone" - no manufacturer uses silicone in its pure form, without additives and plasticizers.
With a very low price (production technology is such that the cost of one tube of sealant costs about 70–90 rubles. Add to this amount the average trade margins of 20–50% and you will see the real price of a quality product).
With a shabby and even more so paper label.

Types of sealants and their scope

Sealants can be divided into 2 main classes:

Single-component silicone sealants - are sold in auto and construction stores in packages for independent use in everyday life. They can be applied immediately, do not require connection with additional materials. Polymerized under the influence of atmospheric humidity. One-component household sealants by chemical composition can be:

Acid sealants - have a pronounced chemical smell. Not applicable for cement and metal surfaces.

Acidic materials can cause allergies and burns to mucous membranes. Therefore, when working with them you need to use respirators, goggles and gloves.

Neutral sealants - cost 30–40% more expensive and have a wider range of applications.

Two-part silicones - are available in bulk packages. They are used for industrial purposes. For polymerization, additional reagents are used.

Scope of use of silicone compounds:

Installation of equipment for bathrooms, showers, kitchen pools and other rooms with high humidity.
Restoration and installation of the outer cladding of buildings.
Repair, installation, insulation of electrical equipment.
Installation of automotive components and assemblies.
Sealing aquarium systems.
Installation and fixation of glass structures.

Advantages and disadvantages

If we consider silicone sealant as a tool, without which it is now difficult to do in the repair of varying complexity, it is necessary to indicate all its advantages and disadvantages.

Consider the advantages of a sealant.

Prevention of mold and the spread of insects on the surface. This is made possible thanks to the fungicidal additives that are included in its composition.
After drying completely, he is not afraid of the effects of cleaning products, even chemical ones.
Using sealant, it will be possible to glue surfaces of various types. For joining ceramics, glass, plastic, wood, rubber with other materials, silicone would be the best choice.
High strength of the material after drying, even with a liquid and elastic structure during application. This is achieved by the presence of silicon in the composition.
A peculiar composition allows already glued surfaces to be mobile and elastic.

Despite such a large number of advantages, there are significant disadvantages of silicone sealant.

There are a number of surfaces that do not bond well with sealant - this is polyvinyl chloride, fluoroplast, polyethylene, polycarbonate and polypropylene.
For application, the surface must be completely clean, therefore it is cleaned, degreased and completely dried. When applied to a damp surface, the properties of the material deteriorate significantly.

Acrylic and silicone sealants have some differences, and first of all, their difference is in the composition: rubber is important in silicone glue, but for acrylic it is acrylic acid. Silicone sealants are used to work with plastic, wood and ceramics, and the acrylic variety is universal. When working with the acrylic option, you can sand it to get a completely flat surface that can be painted. However, there is more severe shrinkage and in the frozen form the material is not so elastic. This type is used for internal work, because with a large amplitude of the temperature regime it can deteriorate.

Silicone sealant provides better adhesion to even and smooth surfaces, it is not afraid of compression and kinks. In view of this, the cost of this option is more expensive than acrylic. Both materials can be both transparent and color, which are used in various situations.

Since silicone sealants can be one- or two-component, it is important to understand the differences. and in this case, revealing certain advantages and disadvantages of each of the options. The one-component composition is most often found, it is used for all construction works by both professionals and amateurs. The simplicity of working with it determines the popularity of this material. The scope of use of sealant is constantly expanding. So, it can be used not only in home repair, it is also useful for working with the machine, eliminating any seams, cracks and joints, it can be used to isolate electrical equipment, and in some cases it is used as a protective layer from moisture.

Two-component silicone is used in industries and in industry. The composition is much more complex, because it combines various elements. It is not used for everyday repair tasks.

How long does silicone sealant dry?

From the moment of application, about 20 minutes pass by the appearance of the film. Full cure takes 24 hours.

In some cases, the duration of complete drying depends on:

Important! When applying strips of material with a section of 4x3 mm, 300 ml of sealant tube is enough for 17-18 meters of linear.

Important! Full hardening of some species ranges from 1 to 3 hours.

Sealant composition and properties

The composition of silicone sealant from different manufacturers may vary significantly, but the base usually does not change:

silicone rubber
an amplifier that makes the material durable after use,
plasticizer - gives elastic properties,
vulcanizer - makes the mixture liquid,
primer - improves contact with different types of surfaces,
filler - determines the color of the sealant.

Properties largely depend on the type of sealant, but there are general indicators.

Silicone is not afraid of ultraviolet radiation.
Withstands moisture, heat, frost and temperature changes, especially when it comes to heat-resistant silicone sealant.
Easy to connect with various materials.
Plastic.
It can be used at temperatures from -50 to +300 degrees Celsius.

Where is silicone sealant used?

The scope is very wide. At home, silicone is used to seal various parts, during the installation of a bath or shower, with problems of sewer pipes and so on. At the same time, silicone sealant is often used for outdoor applications. Namely: closing up cracks in the window frames, imparting tightness to the pipes of the drain, closing the joints during the installation of the roof, etc.

Mixtures are released more often in special hard plastic or soft tubes, which are inserted into the guns for sealants. Small-volume products are packaged in tubes. Large packages, which are mainly used in industry, are sold in plastic or metal cans. The volume of silicone can be different, from 50 ml or more.

The use of silicone sealants

Sealant differences

Depending on which vulcanizer was used in the manufacture, sealants are divided into two types.

Acid formulations have an atypical odor due to acetic acid. You can work with it only with goggles, gloves, a respirator, because the fumes are very toxic and can cause allergies or dizziness. They are used on different surfaces, but at the same time they are dangerous for marble, cement, aluminum!
Neutral, waterproof sealant, in turn, is on amide, alcohol and amine. The smell is normal, not sharp, not toxic. Used on various surfaces.

In addition, silicone sealants are:

single-component - a simple, common type for domestic use. It is easy to use and is used in a wide variety of fields.
two-component - have complex components. They are usually used in industries.

Advantages and disadvantages of silicone sealant

Silicone sealant is used in various fields, so you need to know all its advantages.

Prevents the spread of insects and the formation of mold, so it is often used for the bathroom and similar rooms.
Bonded surfaces remain flexible and movable.
You can glue a wide variety of surfaces.
After drying, the sealant is not afraid of exposure to chemical cleaners. And color types, for example black, blue or other types, also do not change their color.
After drying, the mixture becomes very strong and can withstand heavy loads.

But with all the advantages, the sealant has several disadvantages.

Fluorine plastic, polypropylene, polyvinyl chloride, polyethylene and polycarbonate are poorly bonded with sealant.
The mixture is applied only to an absolutely clean surface, degreased and dry.

Sealant Colors

Due to the high popularity of silicone sealant, manufacturers have begun to make a wide variety of types. So there was a wide range of different colors.

Transparent, it is also colorless used in working with plumbing or where the seam should be invisible. You can use it to protect joints from moisture, for example, when installing furniture in the kitchen or bathroom. Transparent silicone sealant can be painted, if necessary, this will not affect its properties.

The color type (black, gray, beige, red, blue, brown, yellow and others) due to its special composition does not change color and does not become colored. In other words, red will be red and black will be black, and they will not fade. So you need to acquire exactly the color that suits furniture, walls, windows - the place of application.

Colors of silicone sealants

Types of application

Depending on the place of use, silicone sealants are divided into several types.

Bitumen sealant copes very well with cracks in the foundation or basement of buildings.Most often it has a black color. Can hide damage to slate, tiles. It is suitable for fastening a wide variety of surfaces (good adhesion) and is most often used precisely in the construction of buildings or their restoration. It is moisture resistant, not afraid of temperature extremes, heat and frost.
The automotive type is applicable for repairing and assembling a wide variety of automotive parts, including the engine. Popular colors are black, red, blue.

A sanitary, waterproof version of silicone is suitable for rooms with high humidity, for example, for a bathroom, toilet room, sauna, bathhouse, kitchen, pool, etc. It prevents the appearance and development of mold, fungi. Color - white, colorless, beige, blue and many others.
Universal silicone sealant is suitable for sealing gaps in plastic and wooden windows. Bonds wood surfaces well. It happens in different colors, but most often it is used colorless.
Electrical insulation - applicable for repair and assembly of electrical equipment.
The aquarium mixture is not toxic. This is a waterproof and heat-resistant type, most often used for fastening parts of aquariums or for fixing them. Such material dries very quickly, after drying it is not dangerous for fish and other aquarium animals, it has a high degree of adhesion. Fastens mainly glass, ceramics.
Heat-resistant silicone sealant is most often used in industry. They fasten the details of furnaces, pumps, motors, heating appliances, pipes. Often used in electrical work.

Depending on where and for what the sealant is used, it is worth choosing a certain type, then the work will be performed efficiently and there will be no problems over time. If the mixture is not chosen correctly, it may not fit, it is difficult to fasten the parts, let moisture in, cold, have an unpleasant smell or something like that.

Silicone Sealant Manufacturers

Today, there are many companies that produce silicone sealant. Each company has its own priorities, some try to reduce the cost of the product, others try to make it as high-quality as possible, and others are looking for a middle ground. In any case, everyone has flaws, but there are also favorites.

Prices for domestic types - from 2 to 7 dollars. But professional products are more expensive.

Silicone sealant makes repair easy. It is convenient, practical and copes well with the task. When choosing a mixture, it is worth focusing on needs - for what exactly and where it will be used, as well as opportunities. There are good options among expensive and budget brands that are of high quality, but only if used correctly.

How to apply?

In order to start working with silicone sealant, it is important to prepare and purchase everything you need. The first moment will be protective clothing, which should completely cover the skin of the hands, and if possible it is better to wear a jumpsuit and a jacket with a long sleeve to protect the whole body. There are compounds with a more aggressive composition, for them it is advisable to use a protective mask for the eyes and nasopharynx.

The second stage of preparation will be obtaining the necessary knowledge, with the help of which it will be possible to quickly and correctly do all the necessary work.

Sequence of work.

Preparation of workwear and necessary materials.
Work with a surface on which sealant will be applied. It is important that it is clean, dry and fat free. If there are decorative elements, it is better to hide them under masking tape to prevent silicone glue from entering the surface.
To use sealant, you will need a mounting gun, which will simplify the application. For proper installation and work with it, just read the instructions on the package.
The tip of the nozzle on the cylinder with sealant must be cut obliquely. This option allows the material to drain evenly and economically be used in work. If you cut off a flat edge, then the shape of the outgoing substance will be round, and with an oblique cut ellipsoidal, which will minimize the waste of excess material.
Silicone is applied to the surface when the container is at an angle of 45 degrees. Application is in thin strips so that the glue dries faster. After completing the application, the remnants of unnecessary material must be removed with a spatula.

The drying time depends on the type of glue that has been selected and the thickness of the layer that has been applied to the surface. It usually completely hardens in a day, and the first signs of hardening are visible after twenty minutes. When applied to the surface of particleboard and fiberboard, it is better to use a spatula and squeeze out a very small amount of the substance. If there is a goal of creating a perfectly smooth surface on these surfaces, then the sealant is best diluted with gasoline or mineral spirits, the amount of which should be small.

To more accurately understand what exactly needs to be done with a sealant, the first thing you should pay attention to is the instruction indicated on the package. Most often, manufacturers indicate everything that a worker should know in the process of interacting with a silicone agent. If the quality of work is extremely important, then before buying a sealant, you need to pay attention to the timing of its manufacture, and if they are stitched, it is better not to purchase the product.

If the choice is made correctly, then working with silicone glue will be quite simple and comfortable. Once the required amount of product has been applied to the surface, it is important to ensure that all excess is promptly cleaned. This can be done easily with your own hands, but it is important to know the sequence of actions. For fresh solutions it is best to use white spirit, but you need to make sure that it is safe for the surface itself. If this is the case, then as soon as possible it is applied to the area to be cleaned, and all unnecessary is quickly removed.

There is another very effective tool that allows you to flush silicone from the surface, this is Penta 840. The use of this option will simply dissolve the sealant, even if it is dry. The simplest, but no less effective is the use of a soap solution. Having moistened a rag in it, it is necessary to apply it evenly on the surface to be washed off.

The most dangerous coating will be the use of a knife or spatula, with which dried silicone is removed from the surface. You need to use these tools very carefully and without undue rush. Using solvents, it will be possible to remove only fresh or thin areas of silicone, and for more dense, you need to use the mechanical version.
