The application advantages of mica powder in coatings are mainly reflected in the following points:

Synthetic mica powder

First, the diameter and thickness of mica powder are relatively large, which can be as high as 80 or more. Therefore, after mica powder is added to the coating, the formed coating film will be arranged in sheets in layers. The stacked arrangement of mica powder can not only increase the penetration distance of the medium, improve the permeability resistance of the coating, but also improve the scratch resistance of the mica powder.

Second, before and after the addition of mica powder, the test results of the coating film show that the hardness of the coating film with the addition of mica powder is more than double that of the ordinary coating film without mica. Mica powder coatings and ordinary coatings, when tested in the same environment, the boiling water resistance of mica powder coatings is significantly higher than that of ordinary coatings.

Third, mica powder coatings also show higher weather resistance than ordinary coatings in practical applications, which can greatly extend the service life of coatings. Mica powder itself has good corrosion resistance, and at the same time has excellent anti-penetration ability, so the mica powder coating can play a good role in isolating corrosive media. Mica powder is especially suitable as an additive for paint coatings and a filler for some unique coatings. It can greatly improve the anti-aging performance of the coating, enhance the weather resistance of the coating, prevent cracking, discoloration, delayed chalking, atmospheric aging resistance, and strong resistance. Widely used in waterproof coatings, anti-rust coatings, insulating coatings, fire-retardant coatings, road marking coatings, anti-pollution coatings, anti-high temperature coatings and other special coatings.
