Biotite Mica can Improve the Film Compactness

Mar. 06, 2018

The use of Biotite Mica and other mica flake filler, can block the way of molecules of corrosive substances, postpone the progress of corrosive substances. Thereby prolonging the time of anti-corrosion, improving the penetration time, which can improve the compactness of paint film.

The barrier effect is also called shielding effect or labyrinth effect, which is important for anti-corrosion coatings. When using high quality biotite mica powder, the penetration time is extended by three times generally. Because the Mica Powder filler is much cheaper than special resin, it has high economic value and technical value.
