Mica Powder

Product Details:

Main Applications of Mica Powder
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 substitute some expensive raw materials in the paint so as to reduce the production cost.
 Mica powder is also the basic raw material for mica ceramics products.
 Mica powder can be applied in protecting layer of welding rods, conducting wires and electric cables.
 Mica powder can be use as suspended substance in fire-fighting dry powder.
 Mica powder can be taken as a filler, a shelter, a lubricating substance, a drawing of patterns in plastics, rubber, asbestos products and sealing materials.
Mica powder can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid and alkali products.
 Mica powder can be used as coating in models of Cast metal, the brightening material in aluminum and paint in Plating bath.
