Its adhesion performance is due to the presence of silicon dioxide in its products. Silica sol is a relatively good adhesive with extremely strong adhesion. Inorganic coatings doped with silica sol also have good adhesion, which can better fix the product. In the construction industry, adhesives are used in many places. If silica sol inorganic coatings are used, there is no need to spend more products. As long as it is used, problems such as adhesion and heat resistance are solved.
