Features and application of silicone black sealant

Sealing various surfaces and removing cracks is not as simple as it seems. It is very important to choose the right solution, only then the goal can be achieved. One of the best options is black silicone sealant.

Earlier, when there was no such product, it was possible to trim the seams only as a result of long and painstaking work. But the composition, which gives a neutral reaction, was a real salvation. In addition to practical value, the material is useful and a zero level of danger to people, animals and plants.

This mixture has a dense structure and effectively copes with various tasks, such as:

• filling a crack or seam;
• repair and seal aquariums;
• increasing the tightness of individual sections of structures;
• prevention of external damaging effects, especially water.

Consider the most popular samples of silicone black sealant and the scope of their application.

• Kim Tec Tool effectively isolates windows, doors, aquariums and so on. The sealant blocks the spread of moisture, fine dirt (dust) and harmful odors. Use of the waterproof preparation Kim Tec both in the room, and beyond its limits is allowed. Sealant perfectly copes with glass and metal, ceramic and enameled, wooden surfaces.

Even gluing the aquarium with the composition of the specified brand does not require any complex skills, the result will be ready in 30-40 minutes. But full readiness of all seams comes only after 24 hours. Then you can use the product fully. Although silicone cannot be dyed, this manufacturer compensates for this deficiency with an initial assortment of colors. In addition to black, the brand includes a completely transparent (Sturm acetate), color (light gray, brown, beige) and white version of the glue, which allows consumers to find exactly what they need.

• Ceresit CS 25. An ideal sealant is considered a sealant consisting solely of silicone. However, the glue containing a small amount of additives also has high performance and technical characteristics.

• Sikasil SG-20 is one of the most sought after options. It is possible to use such a sealant for fastening parts of the facade, and not just for filling a separate joint or crack. He also proved to be excellent when working with window structures and in the formation of structural glazing.

The mixture is supplied in containers with a capacity of:

1. 310 ml;
2. 600 ml;
3. 20 or 200 l.

The drug is considered initially ready for use and does not contain any solvents, almost does not shrink. The allowable temperature range for operation ranges from +5 to +40 degrees. SG-20 is in excellent contact with almost all surfaces that have to be processed in construction or repair practice. It is stable under moderate ultraviolet irradiation and blocks the development of corrosion on the treated surface.

• Good results and gives the use of sealant Abro 85 g, but the area of ​​its application is already somewhat different - these are automobile engines.Such a composition calmly experiences contact with various technical fluids, with the exception of gasoline. Allows you to work with water pumps and transmission pallet.

• Black Silicone Adhesives Modifications Permatex Adhesive Sealant with the inclusion of synthetic rubber, the seam is equally well kept at temperatures of -60 and +260 degrees. The mixture will harden after 24 hours. Guaranteed stability in contact with all types of automotive reagents, including motor fuel.

• Abro 12-AB will help with the repair or replacement of almost all gaskets used in road transport. With the use of this mixture, the reconstruction of gearbox covers, differential, inlet manifolds and other parts is facilitated.

The formed gasket can have a thickness of up to 0.6 cm. Even after solidification, the mixture retains its elasticity, despite the achievement of high strength. Oil and water, antifreeze will not destroy the prepared compound.

Determine the quality of the sealant is the easiest way to recipe the composition. The best results (as mentioned above) are achieved by the use of a sealant, where, apart from silicone, there is nothing.

This mixture is different:

1. low level of shrinkage;
2. prolonged use;
3. excellent mechanical parameters;
4. increased price in comparison with other adhesives.

A high-quality silicone product forms an extremely strong chemical and physical bond. The high-temperature composition will carry out heating to 300 degrees, but neither Ceresit CS25, nor acetate Kim Tec 101 do not have this valuable property, you will have to choose other mixtures.

The flawlessly high-quality blend is supplied in 310 or 315 ml tubes, the mass of which equals 0.34 kg maximum.

They are considered versatile and inexpensive, but they are not suitable for:

• any non-ferrous metal;
• cement walls, floors and ceilings;
• marble surfaces and parts;
• other substances containing alkali even in trace amounts.
