Sodium Silicate Powder
Sodium Silicate Powder, commonly known as water glass in its solid form, is a white, free-flowing, amorphous powder soluble in water. It is an alkali metal silicate widely recognized for its binding, adhesive, detergent, and corrosion-resistant properties. Sodium silicate solutions derived from the powder form produce a strongly alkaline liquid that is stable and versatile, making it essential in multiple industries. The powder is non-combustible, environmentally friendly in controlled uses, and valued for its adhesive strength, thermal stability, and ability to form films or gels when dried or reacted.
