MIN-U-SIL®
is a high purity, high quality natural crystalline silica
that is available exclusively through U. S. Silica. This ground
silica sand is inherently inert, white, bright, has low moisture and
is at least 99.2% SiO2. |
|
MIN-U-SIL®
is available in five uniform size distributions; 5, 10, 15,
30 and 40 micron. They feature unmatched fineness and consistency of
particle size due to a special processing technique developed by
U.S. Silica.
Special processing
techniques assure controlled particle size distribution, which means
elimination of excessive coarse and fine particles. These
properties, combined with inertness and inherently low cost, make
MIN-U-SIL®
the best quality
filler/extender for a range of applications including paints and
coatings, sealants, silicone rubber and epoxy. |
|
Architectural,
Industrial and Traffic Paints and Coatings
In all types of paints and coatings, the hardness and inertness of
silica yields improved resistance to wear, burnish, abrasion and
stains. MIN-U-SIL Ground Silica, with its narrow size distribution
and bright white color, minimizes resin demand and yields excellent
color acceptance. It is also a low cost filler and extender that can
replace up to 50% TiO2. |
 |
Thermoset
Plastics
The heat resistance, low thermal expansion, chemical resistance and
high dielectric strength of silica make it an excellent filler
choice for a variety of thermoset plastic applications. The narrow
and consistent size distribution of MIN-U-SIL Ground Silica allows
for extremely high loadings. |
 |
Silicone
Rubber
In silicone rubber, MIN-U-SIL Ground Silica is an excellent
semi-reinforcing filler. Its inert nature and high dielectric
strength make it an excellent filler in electrical compounds. The
consistent pH and narrow size distributions allow very high loading
with minimal effect on viscosity and cure rate. |

How
to select a product:
The number in each
product name reflects the U.S. standard for expressing sieve
openings; typically 98% of the grade is finer than the number
expressed in micrometers (microns).
EXAMPLE: MIN-U-SIL
40 means typically 98% or more ground silica is finer than
40 microns.
