china price JW-HP30 silica sol colloidal silica matting agent for oil discoloration
Advantage:
Silica sol is colloidal solution, odorless and non-toxic, and its molecular formula can be written as mSiO2nH2O.
1. As the colloid particles is small,they have rather high specific surface area.
The particles themselves are transparent and won't change the natural color of objects covered by them.
2. As it has low viscosity, it can permeate whatever water can permeate,
and its dispersibility and permeability are good when mixed with other materials.
3. When the water in the silica sol have evaporated, the colloid particles will firmly adhere to the surface of objects and silicon-oxygen combinations will be formed between the particles, which make it a kind of good adhesive.
