U.S. Silica

   

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.

SIL-CO-SIL®, ground silica, available in more than ten uniform grades, ranging from 120 to 400 mesh in topsize.

MIN-U-SIL®, micronized silica, available in five grades, ranging from 40 down to 5 microns in topsize.

    Applications
     
Coatings   As a filler and extender in paint formulations, U.S. 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, U.S. 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. 
     
Plastics and Rubber   Ground silica has found wide industrial application as an additive for plastics and rubber.
