Silica / River Sand
Silica / River Sand
Silica or SiO2 is present in large quantities throughout the earth’s surface in various forms. Its low coefficient of thermal expansion is the principle reason for its use in objects exposed to a wide range of heat and cold. Its principle use is in the manufacture of glass.
It is Natural Grounded Silica Our ground and fine-ground (micronized) silicas are naturally bright white, low in moisture,
Our ground and fine-ground (micronized) silicas are naturally bright white, low in moisture, and chemically inert. They contain at least 99.5% pure SiO2 and are used in many different products requiring rigid control of physical and chemical properties.

Applications :
• Better gloss and whiteness in Paints and Powder coating applications.
• Coatings
As a filler and extender in paint formulations, MASTER . Silica’s fine-ground silica renders paint more resistant to chemical attack because of its acid resistance and improves scrubbability and burnish resistance. Its durability and chemical inertness make it an excellent product for epoxies, coatings, mastics, adhesives, and sealants.
• Ceramics
In ceramics, MASTER Silica’s high quality ground silica provides a bright, white silica base for glazes and bodies, and the consistent size distribution assures reproducible viscosity in slips.
• Plastic and Rubber
Ground silica has found wide industrial application as an additive for plastics and rubber.
