Details: 8~20 mesh is mainly used for building materials, playing an important part in water-proof, fire-proof, heat preservation, heat insulation and decoration. 40~60 mesh is well used for filler to improve the product usability. 60~120 mesh is available for paint admixture, filler, covering agent and rubber lubricant, plastic filler. Moreover, it is also the basic materials of mica ceramics. 200~325 mesh is widely used for pearl pigment. |

Mica powder can be used in paint and coating to reduce the damage of ultraviolet rays or other Light and heat damage to the paint film, promote coating acid and alkali. and insulation, and to t= strengthen its durability , freezing resistance corrosion resistance, water resistance etc. it helps to strengthen the adherence to the layer, improve its intensity, brightness, tenacity and Compaction. As a result ,it is conducive to reduce the ventilation ,to prevent speckle and chaps as well as reduce sediment in the paint. As a prior filler in paint, mica powder can be used to substitutesome expensive raw materials in the paint so as to reduce the production cost.
Mica powder is also the basic raw material for mica ceramicsproducts.
Mica powder can be applied in protecting layer of welding rods, conducting wires and electric cables.
It can be use as suspended substance in fire-fighting dry powder.
