Silica Powder, Ground Silica, 10 Micron (MUS40)

MUS40 is a premium-grade, natural crystalline silica powder with a high purity level of at least 99.2% SiO₂. This ground silica features a controlled particle size distribution, ensuring minimal coarse and fine particles, which enhances its performance across various applications. Its white, bright, and inert properties, combined with low moisture content and a low-cost profile, make it an ideal filler/extender for paints, coatings, sealants, silicone rubber, and epoxy formulations. With a median particle size of 10.5 microns, a specific gravity of 2.65, and a Mohs hardness of 7.0, MUS40 is both highly durable and versatile. It boasts excellent reflectance at 90% and passes 99.2% through a 325-mesh sieve, ensuring superior quality for industrial use.
