Product Description

Product Description

  Silica sol belongs to colloid. It is tasteless and nontoxic, the chemical molecular formula is mSiO2.nH2O.

  Since the colloid grains are minute(10~20nm) and have relatively large specific surface area, the grains themselves are colorless and transparent, so they do not affect the natural color of the material to be covered.

  With low viscosity, it can soak the places whtere water soaks, therefore, it presents excellent dispersion and permability when being mixed with other substances.

  When the moisture contained in silica sol are evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.
