Biotite Mica Can Improve the Compactness of the Film

The use of Biotite Mica and other flake filler, block the way of molecules of corrosive substances, let them bend the road, postpone the progress of corrosive substances, thereby prolonging the time of corrosion protection and improving the penetration time, which can improve the compactness of paint film.

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