Silica sol is a nanoscale particles in water to form colloidal silicon dioxide, non-toxic, odourless, milky white, silica gel superfine particles (10 ~ 20 nm);
With high specific surface area, particle itself is colorless, transparent, color does not affect the covering, and other substances mixed dispersion and permeability is very good;
When silica sol moisture evaporation, colloidal particles firmly adhere to the surface of material, silica is formed between particles, is a good adhesive.
Silica sol is a stable colloidal dispersion of silicon dioxide (SiO₂) particles in water. Produced via hydrolysis of silicon alkoxides or alkaline etching, it features high purity and controlled particle size. The general formula is (SiO₂)ₙ·H₂O, with CAS No. 7631-86-9.
Avoid ingestion or inhalation; wear gloves and goggles. Store in sealed containers at 5–25°C to prevent freezing or microbial growth. Do not mix with strong acids or bases without neutralization protocols.
