Silica sol is a kind of milky colloid, which is a kind of colloidal solution formed by the dispersion of micro silicon oxide colloidal particles with a diameter of 10-20nm into the water. It is mainly used in the refractory material industry, coating industry, papermaking industry and precision casting, and can also used as catalyst material or carrier.
Silica sol is a colloidal solution, odorless and non-toxic.
Because the colloidal particles are fine (10-20nm) and have a considerable specific surface area, the particles themselves are colorless and transparent, which does not affect the natural color of the covered object.
The viscosity is low, and water can penetrate wherever it can penetrate, so the dispersion and permeability are very good when mixed with other substances.
