High purity silica (SIL-CO-SIL®, MIN-U-SIL®)
Our ground and fine-ground (micronized) silica’s 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, is available in more than ten uniform grades, ranging from 40 to 120 in top size. The products properties improve coating hardness, chemical resistance, resin demand and dispersibility.
MIN-U-SIL®, micronized silica, is available in five grades, ranging from 40 down to 5 microns in top size.
Benefits of SIL-CO-SIL® and MIN-U-SIL® are:
- Improved Coating Hardness
- Improved Chemical Resistance
- Low Resin Demand
- Comparable Color and Refractive Index
- Consistent, moderate, near neutral pH
- Dispersibility
Applications are in coatings, ceramics and plastic & rubber. More recently they have become popular in foundry molds.
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 scrubb- 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.
Plastic & Rubber
Ground silica has found wide industrial applications as an additive for plastics and rubber, in particular silicone rubber.
