Due to the deficiencies of the resin material itself in performance, such as poor suspension stability, poor thixotropy, poor weather resistance, poor washability, etc., it is necessary to improve its congenital defects in order to prepare high-quality coatings.

Vapor silica has the functions of thickening, thixotropy, anti-precipitation, extinction, etc., and can improve the process applicability of the coating in production, storage, application and after the film curing. It is an important functional filler.

Vapor silica is an ideal anti-settling agent, which is very effective in preventing the deposition of pigments in the paint system. In the color paste system, proper addition of fumed silica can improve the stability and applicability of the color paste and reduce the impact of the color paste on the paint system.

In the powder coating system, fumed silica can be used as a co-dispersant. Vapor silica can be adsorbed on the surface of the coating powder and form a surface layer on the surface of the powder, which can improve the dispersion and spraying performance of the coating.

The fumed silica can also prevent the sagging phenomenon of the coating during the curing process and improve the thixotropy of the coating. During the construction of the coating itself, due to the rapid volatilization of the solvent at the coating edge, the surface tension is uneven, which is easy to make the coating move towards the edge. The three-dimensional network formed by the hydroxyl group of silica can effectively prevent the movement of the coating and form edges, so that the coating is uniform.
