colloidal silica is the dispersion of amorphous SiO2, with ivory liquid appearance. colloidal silica is a new product produced by JEMT, with new production line, advanced technology, self-contained test instrument, and strict choosing for material. The consistency, particle size is controlled according to the specific requirement of customer. This product has sound controllable bonding strength, quality-controlled, stable capability, and at the leading level in domestic.
1. Since the collid grains are minute (10-20nm) and have relatively large specific surface area, the grains themelves are colorless and transparent , so they do not affect the natural color of the materials to be covered.
2. With low viscosity, it can soak the places where water soaks, therefore, if presents excellent dispersion and permeability when being mixed with other substances.
3. 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 ***** is a good adhesive.
