Sericite/Mica Powder

Sericite/Mica Powder

Cosmetics grade sericite/sericit powderr is a kind of mica, which belongs to silicate mineral with layered structure. Sericite has a wide range of uses, such as rubber, plastics, paint, ceramics, heat preservation, cosmetics, pigments, papermaking, metallurgy and other industries. The crystals of sericite are scaly, and the crystal aggregates are massive, showing gray, purple rose, white, etc., with silky luster.

The application advantages of sericite are mainly reflected in the following points:

  First: Sericite has a relatively large diameter and thickness, which can be as high as 70 or more. Therefore, after sericite is added to the paint, it will be arranged in sheets in the formed coating film. The layered arrangement of sericite can not only increase the penetration distance of the medium and improve the penetration resistance of the coating, but also improve the scratch resistance of sericite.

   Second, before and after the sericite is added, the test results of the coating film show that the hardness of the coating film with sericite coating is more than twice higher than that of the ordinary coating without mica. Sericite paint and ordinary paint, when tested in the same environment, the boiling water resistance of sericite paint is significantly higher than that of ordinary paint.

   Third, sericite coatings also show higher weather resistance than ordinary coatings in practical applications, which can greatly extend the service life of the coatings. Sericite itself has good corrosion resistance, and at the same time possesses the ability to resist penetration, so the sericite coating can play a good role in isolating corrosive media.

   Sericite is particularly suitable as an additive for paints and coatings, and as 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, delay chalking, resistance to atmospheric aging, and strong resistance. It is widely used in waterproof coatings, anti-rust coatings, insulating coatings, fire-resistant coatings, road marking coatings, anti-pollution coatings, anti-high temperature coatings and other special coatings.
