Silica Sol #CSG-08

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.
