Water-based resin coating with matting agent can be divided into organic matting agent and inorganic matting agent two categories. Inorganic matting agent has synthetic silica, kaolin, diatomaceous earth and so on. Organic matting agent is mainly wax, which is the largest amount of synthetic wax and stearic acid, such as metal soap.
According to the distribution of water-based resin coating, matting agent can be divided into filling and suspension type. The inorganic matter is filled and uniformly dispersed in the volume of the coating. Organic matter is mostly suspended, take the water-soluble polyester resin, with the solvent evaporation, extinction agent precipitation and suspended in the polyester resin coating surface. In recent years, with the development of new technologies, the use of wax on the inorganic matting agent, especially silica surface treatment to improve the dispersion of silica performance, easy to produce condensation precipitation defects, to retain the silica extinction efficiency High characteristic. At the same time, the wax feel good, scratch resistance and other advantages also give the silica. At present, wax-treated silica is the best coating agent for the coatings industry.
