Silicate adhesives, fire resistant

These materials are widely used because they are durable, fire-resistant, and inexpensive when compared with organic materials. Inorganic adhesives are based on compounds such as sodium silicate, magnesium oxychloride, lead oxide (litharge), sulfur, and various metallic phosphates. The characteristics of some of the more important commercial materials are summarized. 

These silicate adhesives are fire-resistant and can withstand temperatures up to 1,000 °C if the adhesives cure to a ceramic (homogeneous phase). Since water-soluble silicates are basic, it is... 

Ethyl silicote is o woter-white liquid, soluble in alcohol. It hydrolyzes In water to an adhesive form of silicic acid and alcohol. It is used in lacquers and paint as a pigment binder giving films that are resistant to fire and chemicals and are weatherproof. A less pure, higher silica ester, Ethyl Silicate 40, is also available commerciolly.
