External Wall Anti-corrosion Coating Sericite Mica Application

China Sericite Mica has intuitive effect on anti-corrosion coatings. For exterior wall coatings and outdoor anti-corrosion coatings, the destructive effects of rain and ultraviolet light are still to be considered. The infiltration of rainwater will reduce the strength of the paint film, accelerate the aging, form a porous structure in the paint film after freezing. The acidity will dissolve the filler. These problems must be solved by adding Mica Powder. Mica powder absorbs ultraviolet rays, and the coverage and shielding efficiency is high, which can further delay the aging of the coating. In addition, the flaky filler has reinforcing effect on the paint film.

It is also one of the applications of sericite powder to improve the insulation of coatings. The optical effect is another aspect. The thick Mica Flake reflect well and increase the gloss, while the fine powders cause extinction. Infrared radiation is also one of the functions of mica.
