Using the unique functionality of silicon micropowder, instead of precipitating barium sulfate and talc, it is used in the formulation of blending paints, primers, anti-caries paints, etc. (addition amount 6% to 15%) not only plays the role of filling compatibilization, but also The effects of improving the fineness of the paint, the leveling performance, the hardness of the paint film, the grinding time of the paint, the water resistance, the rust prevention, the corrosion resistance of the paint, the dispersibility of the pigment, and the storage stability of the paint are all remarkable. Furthermore, the melt film coating which is arranged in a certain proportion from silicon micropowder, water, surfactant and water has become a high-quality coating in precision casting due to its low viscosity, convenient use without filling and the like.
