I normally use a fine marble powder in my resin casts (Omyacarb) to strengthen and cut down on resin volume, but a local supplier has gone out of business. Another seller has Sil-Co-Sil, and below is the description:
Silica Flour
Our SIL-CO-SIL® Ground Silica products are produced from high purity silica powder, precision ground from 250 to 5 micron topsize. Our ground silicas are inherently inert, bright white, with low moisture and are at least 99.5% Si02. SIL-CO-SIL’s properties improve coating hardness, chemical resistance, resin demand and dispersibility.
Question is, would this be a suitable substitute? Sounds like it might be basically the same thing, but I was wondering if anyone has any knowledge of this?
Thanks
