Silica Sol
Silica sol is a kind of colloid, it is odorless and nontoxic. Its chemical molecular formula is mSiO2.nH2O. Silica sol has relatively large specific surface area, it is colorless and transparent. It has high bonding strength and high heat-resisting performance(1500-1600℃).
Use
Silica sol can be used as the cohesive agent for various fireproof materials and used for making catalyst and as catalyst carrier; used in coating industry; in paper-making industry and so on.
