Potassium Silicate Liquid / Solution (K2SiO3) CAS 1312-76-1 High Purity

Description

Potassium Silicate Solution (K₂SiO₃) is an inorganic compound supplied in liquid form, widely valued for its excellent binding, adhesion, and chemical resistance properties. With modulus values ranging from 2.0 to 4.1, it provides flexibility for different industrial applications, from construction to coatings and refractories.

The product is a colorless to slightly hazy transparent alkaline liquid with stable density and consistent composition. Its silica-rich formulations (higher modulus) enhance durability, weather resistance, and fire resistance, making it a reliable alternative to sodium silicate in applications where higher performance is required.
