- amplifier – gives the composition strength;
- Vulcanizer – necessary for viscosity and elasticity;
- Clutch primer – improves reliable contact with the surface;
- Silicone plasticizer – gives the composition of additional elasticity;
- filler – necessary to create the volume and color of the material.
Based on the volcanic activity, two varieties of silicone glues are available.
- Acid. This silicone sealant has a characteristic smell, since it includes acetic acids. It is not recommended to be used for marble, aluminum and cement -containing materials. Very harmful to humans, as his evaporation can cause dizziness, various allergic reactions.
- Neutral. Silicone sealant of this type is alcohol, amino, amid. Without a pungent odor. Used for any surfaces without restriction.
There are two categories of silicone sealants: one-component sealants, which are primarily used in homes, and two-component sealants, which are used in manufacturing and have a complex composition.
The composition’s primary attributes enable its application on a variety of surfaces with varying textures. These include:
- resistance to a change in weather conditions (frost -resistant, waterproof);
- increased adhesion with different details and building materials;
- stability to UV rays;
- plasticity, which confirms high accommodation of movement (above 20%);
- heat resistance (can be used at temperatures from +300 to -50 ° C).
Types of sealants and scope of their application
When doing repair work, silicone sealant is an essential, or better yet, indispensable material. Today’s market for adhesive compositions for the construction industry offers a variety of options. Regarding appearance, you can emphasize:
- Colorless sealant. It is used in the repair and installation of plumbing, in the places of connection of the panels of the shower cabin, at the junction between the bathroom and the wall. Due to the fact that the material is quite waterproof, water leaks, as well as the appearance of mold, can be avoided. Also, transparent sealant is used in the assembly of kitchen furniture.
- Color sealant. The surface treated with silicone is poorly stained. To avoid defects, get adhesive material with colored pigment. In construction stores, such products are represented in the next tinted range: white, red, black, yellow, beige, brown, etc.
The following categories of products are distinguished based on their field of use:
- Bitumen sealant. Designed to eliminate cracks in the basement and foundation, with damage to the roof of tiles and slate. The scope of the material is different. Surfaces and parts can be plastic, metal, wooden. The main characteristics of the material: moisture resistant, resistant to temperature changes, creates adhesion of high strength.
- Universal sealant. Allows you to tightly install glass in wooden window frames tightly. Thanks to increased adhesion, it is possible to achieve a complete absence of drafts. The material for outdoor work should be chosen colorless so that it is not noticeable on the wood.
- Aquarium silicone sealant. The composition should not be toxic. It has flexibility and elasticity, high adhesion, drainage, does not spread, it dries quickly. Can be used to process joints of showers, ceramic and glass products. This is the best option for the aquarium.
- Sanitary silicone sealant. This is an indispensable universal assistant for processing rooms with high humidity. Its main difference from other materials is that it contains antifungal and anti -bacterial substances.
- Heat -resistant sealant. It is used for industrial work, assembly of pumps, engines, furnaces, when sealing heating pipes, chimneys. Thanks to its composition, the material is used at temperatures from +300 to -50 ° C. In this case, its elasticity and elasticity are completely preserved. High -temperature sealant is indispensable and during electrical work.
Soudal and Sealant of the Moment are two of the most well-liked products. The other manufacturer in the assortment offers various silicone-based adhesives designed for distinct uses. For instance, the moment the tool is meant for both internal and external work. is a fast-setting mounting foam.
Mirrors and other panels are installed during the moment of herment. Because of its universal composition, you can use the material on any surface.
It is preferable to use Soudal’s silicone sealant for small repair tasks. Double-glazed window seals are made with it. Its primary attributes include heat resistance, elasticity, and UV resistance.
The Sudal company manufactures colorless or white sealant. On the surface that has been treated, the material does not leave bubbles.

How to apply silicone sealant
Think about the step-by-step procedure for applying the sealer. Take a silicone moment of the herment, for instance:
Put on overalls before beginning work, and make sure to wear protective gloves to prevent material from getting on your hands.
2. Dust, degrease, and then dry the surface. Using masking tape, create a decorative surface to evade the silicone composition’s outcome.
3. Applying a silicone moment with a mounting gun is more practical. The sealant’s packaging usually includes instructions on how to install it.
4. To ensure sealant is applied evenly, cut the cartridge’s edge along the oblique.
5. Use silicone, holding the sealant at a 45-degree angle. To speed up the drying process, try to make each strip as thin as possible. Connect both sides for a complete clutch. A spatula can be used to remove the extra material.
Regarding drying time, everything will depend on the kind of sealant used and the layer’s thickness. The material takes around 24 hours to harden on average; after the first 20 minutes, a hard film forms on the surface.
Apply a thin layer of sealant with a rubber spatula to the edges of the fiberboard and chipboard products to make them sturdy and waterproof. However, you can dilute silicone sealant with a small amount of white spirit or gasoline if you want the surface to be perfectly flat. Furthermore, he will maintain his waterproof and heat-resistant properties even after fully drying out.
The package provides a precise explanation on how to use silicone sealant. It usually explains the purpose of the material, how to apply it to the surface, when it will completely dry, and when it expires. Adhesive mixtures with a shelf life that has passed should not be bought at a promotional price. Since such material loses its properties, repair work should not be done on it.
