Application performance of Talc Powder in Coatings Industry
Because talc for coating has excellent physical and chemical properties, such as lubricity, adhesion resistance, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, strong adsorption and so on.
As a filler, the application of talc powder in coatings is mainly reflected in:
1.talc for coating has high whiteness, uniform particle size and strong dispersion.
2. It can play the role of skeleton.
3.talc for coating can reduce manufacturing cost.
4.talc for coating can improve the hardness of paint film.
5.talc for coating can increase the stability of product shape.
6.talc for coating can increase tensile strength, shear strength, bending strength, pressure strength, reduce deformation, elongation, coefficient of thermal expansion.
As the filler of polyurethane waterproof coating, talc powder can not only reduce the volume shrinkage during curing, improve the wear resistance and adhesion of the coating, reduce the cost, but also make the coating have good storage stability and heat resistance.
