3、 Main use of the product
Widely used in composite materials (electronic components, packaging materials, high-performance rubber products, automobile shells, molds), paper making ceramics , building materials, rubber, plastic paint 、 coating , chemical industry, welding electrode, nylon, metallurgical protective slag and as asbestos substitute.
4、 Main functions of the product
When used in plastics, the impact strength of products can be increased, the fluidity can be enhanced, and the tensile strength, linear tension and die shrinkage can be improved.
It can not only improve the toughness and durability of the coating, but also maintain the smoothness and good gloss of the coating surface. Moreover, it improves the scrub resistance and weathering resistance, reduces the oil absorption of paint and ink, and maintains alkalinity, which has corrosion resistance. High quality and bright color paint can be obtained, and it has good uniformity and ease aging performance. The coating can obtain better mechanical strength, increase durability, enhance adhesion and corrosion resistance. It also has good coverage and adhesion.
