Generally, low gloss can be achieved by adding matting agent to form a rough surface [].A large number of matting agents have been introduced into waterborne polyurethane, and the most commonly used therein is known as silica powder with different particle size [9,10].However, due to incompatibility with the organic polyurethane, the matting agents were poorly dispersed in WPU, which resulted . As a coating film dries, wax particles are transported to the film surface as a consequence of the turbulence flow induced by the water evaporation. Because of the large particle size, protruding wax particles create a certain degree of micro-roughness, induced as the film shrinks. Polymer latex is widely used in different fields and industries.
