Sodium silicate Properties:
Sodium Silicate, also known as water glass, it has two forms: liquid and solid.The liquid is common, colorless clear or light gray deup. The solid is light blue or light green crystals, transparent or semi-transparent .Sodium Silicate is made from sodium oxide and silicon dioxide, the molar ratio between them called modulus, the physical property and usage would be different if the modulus changes.

Sodium silicate Usage:
sodium silicate gunning material when repair is mainly used in the furnaces, the amorphous refractory materials, foundry binder in foundry industry, insulation materials, welding electrode binder, acid-resistant cement, alumina cement and other additives in cement, coating industry, detergent industry, soap industry, and in addition to the agent, filling agent and corrosion inhibitor in synthetic detergent, and at the same time can be used for the liquid foam alkali can applicable scope. User requirements of special specifications can be consulted.
Sodium silicate Safety Protection:
Keep in a tightly closed container, Store in dry; cool; ventilated area, keep away from moisture and avoid physical damages
