Ground silica. Acts as a semi-reinforcing filler. In comparison to other natural minerals, SIL-CO-SIL® 63 offers an improved chemical resistance, low resin demand, dispersibility as well as comparable color and refractive index. The consistent pH and narrow size distributions allow very high loading with minimal effect on viscosity and cure rate. It is low in moisture, chemically inert and possesses acid-resistant durability. Used for rubber and epoxy.
