Description of Potassium silicate

Potassium silicate, also known as potassium water glass, is a colorless, slightly colored transparent or translucent viscous liquid with a pH of 11~13. The relative density and viscosity of the product vary with the product model, the relative density is

between 1.16 ~ 1.45 (20 ℃). Potassium silicate can dissolve in water and alkaline solution, insoluble in alcohol and organic solvents, and free gel by interaction with acid. It can react with the hydrophilic group on the surface to form a film.

Applications of Potassium silicate:

Powdery Instant Potassium Silicate is white powdery substance, can fast dissolve in water, resistant to cold and good uniformity.

It is a special foamed alkali convenient to be used, transported and stored.

Molecular formula: K2O·nSiO2·H2O, n varies with the specification the uses.

Powdery Instant Potassium Silicate has better solubility and higher adhesion compared with FS powdery instant sodium silicate.

Powdery Instant Potassium Silicate is widely used as adhesive in fireproof material, as auxiliary in drilling liquid of oil field and other special fields.
