Silicone Adhesive: Brief Description

Silicone adhesive is a composition that includes a variety of catalysts, hardeners, fillers and dimethylpolysiloxane rubber.
The present agent is characterized by increased adhesive and vulcanizing properties. Silicone sealant polymerizes within 24 hours.

Synthetic mass is used in industry, construction for gluing a variety of surfaces. High adhesion properties of the adhesive contribute to the formation of an ultra-strong molecular bond. As a result, the seams are quite strong. For example, in order to break one cm2 of the sealed slot, it is necessary to apply an effort of 200 kilograms. Silicone adhesive exhibits excellent adhesion properties to most natural and synthetic materials. This adhesive perfectly glues silicate and organic glass, aluminum, steel, ceramics, polycarbonates, copper and even concrete. Vulcanization of materials is carried out without the release of toxic and corrosive substances. Do not confuse silicate glue with silicone. This, as they say, absolutely different things. Silicate glue is sometimes called "liquid glass" because it represents an aqueous solution of alkali metal polysilicate (sodium and potassium). As a rule, silicate glue is used for gluing cardboard or paper. Oddly enough, the scope of its use is quite wide. This adhesive is used for the production of acid-resistant concrete and cement, the preparation of fire retardant paints and coatings for wood, impregnating fabrics, coating welding electrodes, cleaning machine and vegetable oil.

Silicone adhesive should have the following characteristics:

- heat resistance;

- high adhesion to a variety of properties;

- frost resistance;

- resistance to ultraviolet radiation;

- the ability to seal and glue different materials in different combinations;

- high plasticity of the seam;

- durability.

It should be taken into account that silicone glue with acid curing type releases a small amount of acetate during hardening, which in turn causes destruction and corrosion of non-ferrous metals, marble, and other natural materials. A sealant with a neutral type of curing can be used to glue or seal the bases of any materials, both natural and synthetic, because it does not release aggressive compounds into the external environment. During the curing process, a neutral substance is released: methyl ethyl ketoxime.

The main advantages of silicone glue include the following indicators;

- a wide range of colors;

Curing at room temperature;

- high plasticity after curing;

- ease of application;

- strong adhesion to different materials (painted, enamelled steel, glass, aluminum, ceramics, technical plastics).

Silicone adhesive for aquarium - a monocomponent high-strength sealant for glass. Can be used in industrial environments where high-strength bonding is required along with rapid vulcanization and high resistance to ultraviolet radiation. Specialty glue will provide reliable connection of aquarium parts up to 3,500 liters.
