GRF-72R Main Feature
1. fine particle size
2.special for rubber especially for tire
Kaolin for Filler Series
1.As aluminum silicate pigments and multi-functional additives, the product has high whiteness, few impurities, and strong chemical inertia.
2.They can be used in waterborne and oily paints, putties and sealants because of their ease of dispersion in water and oil systems.
3.The product has good hiding performance, can adjust the gloss of the coating, improve the mechanical properties of the coating, the inventory stability of the coating, brushing performance, and partially replace titanium dioxide to reduce costs.
