What is included in silicone sealant?

Most professionals working in the construction industry are well aware that silicone sealant is a special composition that has the property of hardening at room temperature. With all this, an airtight coating is created that can withstand the effects of external causes, including water.

It is curious that this material, which has the appearance of a viscous composition, is made from a very hard natural element - silicon. More precisely, polymers are made from silicon, which are the basis of silicone sealant.

In addition to polymers, the sealant includes the following elements:

silicone rubber (it is used as a base and therefore must be of the highest quality);
vulcanizer (a special additive that turns a mass of material into rubber);
plasticizers (give elasticity to the material);
extenders (depending on the external influence, they can increase or, on the contrary, reduce the viscosity of the sealant).

In addition, depending on the manufacturer and purpose of the material, additional additives can be added to its composition that act on silicone depending on the scope of its application.

For example, ingredients that affect coloring are added to sealants. Special elements are added to sanitary products that prevent the development of fungus and also destroy harmful bacteria.

How long does it take for silicone sealant to dry?

The drying time of the sealant is determined by the components of the product and its purpose. There is a quick-drying type of material, and there are sealants that dry for quite a long time. The sealant hardens and hardens in the following time:

4-6 hours is the period during which the acid variety hardens.
It takes 24 hours to dry the neutral silicone type.

The drying time of the universal product may vary depending on the influence of different criteria. The period could be like this:

The top layer of the substance will dry in 15 minutes if applied in large quantities. The top layer will still not stick to your hands. But the inner layers will polymerize 2 mm per day.
The period of curing, hardening and hardening can be accelerated by 2 times if you provide warmth in the room. When carrying out external work on the street, it will not be possible to influence this indicator, so it is better to wait more time than the manufacturer advises.

How to properly store silicone sealant from an open tube

These days, many repair and construction work require the use of a special product, specifically silicone sealant .

It will be used during a variety of procedures, from laying pipelines to installing various finishing materials (plastic, euro-boards, laminate). Today, modern sealants have a number of positive qualities including:

high performance characteristics;
ability to withstand heavy loads;
temperature changes;
aggressive environment;
exposure to liquids;
UV radiation;
high voltage.

Also, a big advantage of such compositions created on the basis of silicone is their adhesive properties, or in other words, the ability to hold a variety of materials together. However, using sealant requires certain skills.

How to Preserve Open Caulk

For example, a person who decides to use this product should know how to preserve silicone sealant after opening the package, namely the tube.

Sealants for temperatures up to +250 degrees (seals)

Sealants are used to create very elastic seams (which can withstand being stretched twice).
It is a pasty, semi-liquid mass of blue or red color. The sealant retains its heat-resistant qualities in the range from -40 to +250 degrees Celsius, so it is often used for application to the outside of modern chimneys (sandwich pipes), and its high elasticity allows them to be used on structures with strong shrinkage.

The recommended temperature for applying sealants is from four to thirty degrees Celsius, and the maximum permissible seam depth is no more than 0.6 cm, otherwise there is a risk that the heat-resistant product will not harden in the depths.

Application of silicone sealant

Silicone sealants are connecting, sealing agents created on the basis of silicone rubber, which have high adhesive properties and, upon contact with moist air, begin to polymerize. Thanks to this, silicones can be used for absolutely any task related to connection and sealing. At the same time, it is not necessary to use the entire tube of silicone at once. Using the above tips, you can “preserve” the material and use it when necessary.

Silicate-based compounds

Sealants with heat-resistant properties are made based on silicates. Non-flammable compounds are designed to withstand extreme temperature loads and are used in areas of heating systems with open flames and high-temperature heating.

The fireproof sealant can withstand up to 1500℃. The compositions have high adhesion to almost all known building materials and, due to the high temperature threshold, can be used in any work.

Using heat-resistant sealants, cracks are filled, leaky joints are sealed, and gaps are sealed, and there are practically no temperature restrictions.

The main advantage of fire-resistant sealants is their ability to expand at high temperatures and create a non-flammable dense layer of foam coke, which becomes a serious obstacle to the penetration of smoke and the spread of fire into adjacent rooms.

After hardening, a hard, inelastic layer is formed. This inelasticity of the material has its advantages. Fire-resistant sealants can be painted. It will not fall off or crack. Disadvantages include weak adhesion to smooth surfaces.

What is included in silicone sealant?

Most specialists working in the construction industry are well aware that silicone sealant is a special composition that has the property of hardening at room temperature. This creates an airtight coating that can withstand the effects of external factors, including moisture.

Interestingly, this material, which has the appearance of a viscous composition, is made from a very hard natural element - silicon. More precisely, polymers are created from silicon, which are the basis of silicone sealant.

In addition to polymers, the sealant contains the following elements:

silicone rubber (it is used as a base and therefore must be of high quality);
vulcanizer (a special additive that turns a mass of material into rubber);
plasticizers (give the material elasticity);
extenders (depending on external influences, they can increase or, on the contrary, reduce the viscosity of the sealant).

In addition, depending on the manufacturer and purpose of the material, additional additives may be added to its composition that affect the silicone depending on its scope of application.

For example, building sealants contain ingredients that affect coloring. Special elements are added to sanitary products that prevent the development of fungus and also destroy harmful bacteria.

Advantages and disadvantages

Fireproof sealants have a number of advantages that set them apart from materials with similar purposes:

resistance to high temperature action, no burnout (for a number of products),
high degree of adhesion to most building and finishing materials,
absence of hazardous substances in the composition, release of toxins when heated,
dielectric properties,
absence of deformation, cracking due to elasticity,
the ability to withstand vibration, UV radiation, radiation exposure, the influence of moisture, detergents, microbial activity,
long period of operation (up to 40 years),
Availability of convenient shapes and various volumes on sale.

The disadvantages include the increased cost of such products compared to conventional sealants, but this is compensated by a lot of advantages.

Features of the material

The main thing to remember about silicone sealant is that it is a universal product that is convenient to use to eliminate any minor problems or leaks, as well as major construction procedures, installation and fastening of structures and equipment. It will provide reliable sealing both indoors and outdoors, no matter how long it dries. This type of material is suitable for installing plumbing fixtures and plumbing equipment. But its application will also be relevant in other situations:

READ Do-it-yourself pitched roof on foam blocks

The adhesive composition can be used to fill cracks when installing windows, doors and other structures. It can be used with high efficiency when laying electrical cables, cords, and wires.

One of the main advantages of mixtures is protection against the spread of fungus and mold. Sealant is also used in larger areas, such as mechanical engineering and machine tool building, and is an important and necessary material when disassembling element assemblies.

Dehumidify the air

Low air humidity around the packaging also contributes to an increase in shelf life. This is especially true for silicone and polyurethane sealants. To achieve this goal, buy a desiccant, such as silica gel, that contains silicic acid, which absorbs water well. Place it in a tightly sealed container and store your sealants there too. The air inside will very quickly become dry, which is what you need.

As a container, you can use any hermetically sealed container or a regular plastic bag. It is recommended to purchase silica gel, which changes color as moisture is absorbed. Once a month, replace used granules with new ones.

How can you preserve the sealant after opening the package?

Most often in everyday life, silicone sealants are used to troubleshoot problems, glue different parts, and seal seams around plumbing fixtures and pipes. However, usually a very small amount of material is needed to perform such work.

And then the question arises of how to preserve the remaining sealant in the packaging. After all, this material begins to quickly transform into a polymer immediately after contact with oxygen.

To preserve the sealant, you can take the following steps:

close the hole formed in the tube using tape or cellophane film. This way, air will not be able to penetrate into the packaging;
You can also screw a self-tapping screw into the hole, first releasing a little sealant .
You can also simply transfer the silicone, for example, into a glass vessel and close it tightly.

Is the sealant drying out in the spout? This is no longer a problem!!!

By acting in this way, you can save the material and thus save money on its purchase in the future.

High temperature sealant application process

First of all, you need to cut off the sealed cap from the cartridge with a sharp knife - this is what closes the tube. In this case, it must be cut across its entire width. Then the following range of activities is carried out:

the spout is screwed on - it must be pre-cut, as indicated above in the article;
then the tube with the material is installed in a construction gun - its preparation should be carried out based on the features of its design;
after all of the above, proper preparation of the surface for further work begins;

The object is thoroughly degreased, cleaned of dust, dirt and residues of building materials. If the surface is extremely smooth, then it is pre-treated with sandpaper. This step will provide enhanced adhesive properties. After sanding, you need to clean the surface from any remaining abrasive material.

Then the surface is degreased and dried. At this stage, it is advisable to use a hair dryer as it will speed up the work.

after the surface has dried and additional checks, you can begin applying the sealant;
When using high-temperature sealant, the latter must be allowed to harden. As a rule, the time required for complete hardening is around 24 hours.

After application, it is necessary to burn the material with a gas burner. By implementing all of the above measures, you will ensure sealing that can withstand high temperatures up to +1500 degrees inclusive.

Now you can safely use the stove and not be afraid of the risk of an emergency - it is completely eliminated by high-quality sealing.

Silicone sealant: composition

Silicone sealant is an elastic, multi-component compound that hardens at room temperature, creating an airtight seal. Oddly enough, viscous silicone sealant is made from silicon, one of the hardest materials in nature. It is from silicon that the polymers that form the basis of silicone are made.

In addition, the silicone-containing sealant includes:

Silicone rubber (it is the main one, and therefore must be of high quality);
Rubber vulcanizer (converts elastic, “raw” mass into rubber);
Adhesion activator (strengthens the adhesion of the composition to materials;
Extenders (depending on external factors, increases or decreases the viscosity of silicone);
Plasticizer (increases the elasticity of the composition).

The composition of the connecting, sealing agent, depending on its purpose, may include special additives that affect the scope of use of silicone. Thus, construction sealants may contain tints that affect their color. Sanitary sealants must contain fungicides and biocides to prevent the appearance of mold, mildew and other pathogens.

What are the differences between heat-resistant sealants?

The main task of the sealant is to create a strong insulating seam (or layer) between the parts.
As a rule, the base is made of special heat-resistant silicone. Metal powder, minerals and other components are added to this colorless elastic mass to enhance the effect of the heat-resistant composition.

Heat-resistant sealants must meet very strict criteria.

In addition to heat- and heat-resistant sealants, the line of sealants also includes two-component heat-resistant adhesive compositions based on epoxy resin that can withstand high temperatures.

What is silicone sealant used for: how to use the composition

The purpose of silicone sealant was mentioned above. Thus, a silicone-containing composition is used to fill cracks and crevices for the purpose of sealing them and gluing various materials together.

The scope of application of the sealant depends on its composition, ability to withstand extreme temperatures, and aggressive influences.

Thus, one-component household silicones are used for treating cracks around bathtubs, sinks, toilets, filling joints between tiles, and gluing finishing materials to various surfaces.

Two-component silicone sealants can be used for:

Repair of wooden, concrete, brick surfaces (acrylic silicones);
Sealing PVC boards (polyurethane sealants);
Repair of metal structures, equipment (thiokol sealants);
For the assembly of electrical equipment (electrical insulating silicone sealants);
Sealing of chimneys and joints of heating equipment (high-temperature, heat-resistant sealants).

In addition, bitumen construction sealants are used for: repairing bitumen roofs; waterproofing of wooden and metal structures, foundation and drainage systems.

Heat-resistant sealant "Silotherm EP-71"

This sealant is prepared on the basis of a durable silicone elastomer. It is used for sealing seams and joints on building structures, installing fire protection systems, sealing cables, connecting and transition couplings, and installing double-glazed windows.

A variety of sealant "Silotherm EP-71M" is used to create fire-resistant electrical insulating coatings and provide anti-corrosion protection. The Silotherm EP-71 kNS version has increased elasticity and is therefore suitable for highly deformable joints. All means are different:

radiation resistance,
moisture resistance,
ability to coke under the influence of fire,
explosion safety,
frost resistance,
ability to electrically insulate.

The use of sealants will help strengthen fire protection and reliably seal all seams and cavities. You should not save money on their purchase: it is better to choose a reliable product from a well-known brand to take care of your safety.

Silicone sealant: varieties

Household one-component silicones are divided into:

How to keep silicone sealant in a tube from drying out. The latest development in science #silicone #construction

Acidic (universal). Such silicones are based on acetic acid. It is its smell that can be felt after applying the composition. Such silicones do not cost much, have good adhesive properties, and their drying time is 4-6 hours. The main disadvantage of acid sealants is their incompatibility with non-ferrous metals and delicate, alkaline finishing materials (for example, marble). In addition, such sealants are not recommended for use in rooms with high sanitary and hygienic standards.
Neutral. To produce neutral sealants, alcohol or ketoxime is used. The disadvantage of neutral sealants is their high price compared to acidic ones. In addition, neutral sealant dries, on average, at a rate of 2-4 mm per day.

According to their intended purpose, silicone-based sealants are divided into: repair and construction, special, automotive. For example, they include sanitary sealant for plumbing work, aquarium silicone for sealing aquariums, terrariums, joining glass elements, adhesive-sealant for gluing car windows, etc.

How not to make mistakes when buying?

No one is immune from purchasing low-quality products, even in chain construction hypermarkets. To avoid flaking or cracking of the sealant that took so much effort to apply, pay attention to the following points:

A damaged label indicates a violation of storage rules. If the tube has been frozen and thawed, its contents are unusable.

A weight of more than 0.34 kg with a volume of 310 ml indicates a high content of impurities.

The inscription 100% silicone or the price is too low are one of the indicators of unscrupulous manufacturers.

A reliable basis for long-lasting sealing is a combination of the following factors: the purchase of high-quality material taking into account the type of surfaces being treated, adherence to application techniques and conscientiousness in performing the work.
