ASI (alkali silicate)

Alkali silicate plays an important role in surface technology. This compound, also known as water glass, is often used to coat and seal surfaces. Their chemical resistance and ability to bond firmly with a variety of materials make alkali silicates an ideal means of protecting and improving surfaces.

Alkali silicates are often applied as a primer or protective coating on concrete and metal surfaces. In concrete, alkali silicate is used to seal and harden, increasing the strength and abrasion resistance of the surface. For metallic surfaces, an alkali silicate coating protects against corrosion and oxidation, which is particularly beneficial in aggressive environments.

In addition, alkali silicate offers thermal stability, which makes it possible to protect surfaces from high temperatures. This property is particularly useful in applications where heat resistance is required, such as refractory coatings and insulation systems.

Another advantage of alkali silicate in surface technology is its environmental friendliness. Compared to organic coatings, alkali silicates do not contain volatile organic compounds (VOCs) and are therefore less harmful to the environment. This makes them an attractive option for sustainable and environmentally friendly coating applications.
