coating for concrete, stone, brick and exterior walls.
concrete, and filler for cement mortar to improve the strength of cement mortar.
Mica powder is a kind of non-metallic mineral, which contains many kinds of components, including Sio2 and Al2o3.Mica powder has good elasticity and toughness. Insulation, high temperature, acid and alkali resistance, corrosion resistance,strong adhesion and other characteristics, it is a good additive. It is widely used in electrical appliances, welding electrodes,rubber, plastics, paper, paint, paint, pigment, ceramics, cosmetics, new building materials and other industries, with a widerange of applications. With the continuous development of science and technology, people have opened up new application areas.
