Mica Powder
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 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.
