Sodium Silicate Powder, High Alkaline


Sodium Silicate Powder, commonly known as Water Glass, is a fine, white, highly alkaline powder that dissolves easily in water, forming a hazy, colorless colloidal solution. It is a versatile material with a pH of 11.5 in a 1% solution, making it suitable for a variety of industrial and specialized applications. Sodium Silicate Powder is commonly used in non-flammable coatings, refractory cements, adhesives, and binders. Additional uses include applications in agriculture, detergents, and construction materials. With a weight ratio of SiO₂/Na₂O at 2, and chemical composition including 27% Na₂O and 54% SiO₂, this powder is effective and efficient in its purposes. Its sensitivity to moisture necessitates storage in tightly closed containers.
