Product Description
MUS40 is a high purity, high quality natural crystalline silica. This ground silica sand is inherently inert, white, bright, has low moisture and is at least 99.2% SiO2.
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 MUS40 the best quality filler/extender for a range of applications including paints and coatings, sealants, silicone rubber and epoxy.
