This is a high purity, natural crystalline silica that comes from quartz quarries in Oklahoma. It is a fine ground silica sand that is inherently inert, white, bright, and is at least 99.2% silicon dioxide. Special processing assures a controlled particle size distribution, which eliminates excessively coarse and fine particles. These properties, combined with its inertness and low cost, make silica an excellent filler and extender for paint.

The hardness and inertness of silica improves resistance to wear, burnish, abrasion and stains. The narrow size distribution and bright white color, minimizes binder demand and yields an excellent color. It is also often used to replace as much as 50% of titanium dioxide in paint formulations.

Silica (SiO2) is a compound formed from silicon and oxygen. Because oxygen is an abundant element and silicon is the second most abundant element in the Earth's crust, the formation of silica is quite common in nature. Silica sand, the substance used to derive pure silicon, is made of quartz, which is the most common form of silica found in nature. Crystalline silica exists in seven different forms. The three major forms, quartz, cristobalite and tridymite, are stable at different temperatures. Within the three major forms are subdivisions. Crystalline silica is ubiquitous, being in rocks from every geologic era and from every location around the world.

Recommended Uses

Add silica to paint and mediums to create textural and bodying qualities in oil paint without affecting the color. Silica has little color in drying oil, so it can be added to oil paint without affecting the tint of the color. Due to its hardness it tends to add a discernible texture to paint. Add to chalk or gesso to add texture or 'tooth' in chalk or gesso grounds.

Health and Safety

WARNING: This product contains crystalline silica, which can cause silicosis (an occupational lung disease) and lung cancer. For detailed information on the potential health effects of crystalline silica, see the Material Safety Data Sheet.
