Construction

Our superior high purity and incredibly white silica ensures your products are durable yet consistent for all your building applications. Naturally-occurring ultra-pure SiO2 (greater than 99.997%) is geologically rare. Sinova is able to provide you with a long-term solution that is carbon-neutral with 70-90 years of availability. Sinova’s hard quartz provides the building blocks to create a hardened compound that provides a good hold, high strength, and excellent durability.

High purity silica contributes critical performance properties such as brightness and reflectance, colour consistency, and oil absorption. In architectural paints, silica fillers improve tint retention, durability, and resistance to dirt, mildew, cracking, and weathering. Low oil absorption allows increased pigment loading for improved finish colour. In marine and maintenance coatings, the durability of silica imparts excellent abrasion and corrosion resistance.
