Dry Chemical Powder Silicon Dioxide For Plastic

What are the important indicators of silica for coatings? Silica is mainly used in coatings for buildings, automobiles, railway vehicles and ships, and is also used as a coloring pigment in gray and other colors of coatings. Silica has high blackness and tinting power and stable price, so it is an indispensable black pigment in the coating industry. Now most coatings use silica as a coating processing product. Important indicator of silica for coatings: silica blackness Blackness is the main indicator of silica for coatings. When used for coloring black coatings, such as black car topcoat, the higher the blackness of the silica used, the better. When silica is used for coloring, too much melanin and too little addition can easily cause color differences in different batches of coating products, so silica with lower blackness is required. Important indicator of silica for coatings: silica tinting power Tinting power (tinting strength) is the coloring ability of silica when white o…
