GROUND
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. |
| Plastic and
Rubber |
Ground silica has found wide industrial application as an additive
for plastics and rubber. |
