Potassium Silicates are a family of chemicals with a range of physical and chemical properties. The character of the products is determined by the ratio of silica to alkali and by the solids content. Although Potassium Silicates resemble Sodium Silicates in their basic composition, their industrial uses vary significantly.
Compared with Sodium Silicate solutions, Potassium Silicate solutions are somewhat more viscous. Their viscosity is affected by concentration and temperature. The addition of a small amount of water very quickly changes the syrupy solution to a solution approaching water in viscosity. Viscosity also diminishes when the composition becomes more alkaline without change in solids content. Like all a hydrous silicate glasses, Potassium Silicate products soften at high temperatures and gradually become fluid enough to flow freely. Potassium Silicate solutions are not tacky, and mortars prepared from them does not stick to the trowel. This can reduce labor costs for brick laying in acid-fast construction.
Anhydrous Potassium Silicate glass is less conductive, i.e. it has greater electrical resistance, and can therefore be used in cementing electrical components, bonding reconstituted mica, inputting compounds, etc.
