The refractive index of silica 1, 46 is close to that of film-forming resin, and has no effect on the color of paint film. Migration to the surface of the paint film during the film forming process can produce the expected roughness of the paint film surface, significantly reduce its surface gloss, and is a good matting agent. The extinction effect mainly depends on the three properties of the product: porosity, particle size and surface treatment. When using white carbon black, pay attention to the matching with the thickness of the paint film. Using white carbon black with very fine particles in the thick film paint is a fine surface that cannot produce appropriate roughness. On the contrary, if using white carbon black with particle precipitation method in the film paint, although its extinction effect is very good, the roughness of the paint film surface will not be acceptable to most users.
