1. Mica powder:
Mica is a layered silicate with a flaky structure, a large diameter-to-thickness ratio, stable chemical properties, acid and alkali resistance, high temperature resistance (above 600°C), good electrical insulation, good wear resistance and abrasion resistance. It is an excellent functional filler. It is arranged in parallel and stacked in layers in the coating, which strongly blocks the penetration of corrosive substances into the coating film, improves the water resistance and salt spray resistance of the paint film, and enhances the anti-corrosion performance. At the same time, mica has a unique ultraviolet light shielding function, which can improve the weather resistance of the coating, prevent cracking, delay discoloration and powdering.
