Special product for solvent borne coating and plastic extrusions system. The product is wet ground by imported mill which results in a good particle size distribution. The product surface is densely coated with inorganic compounds of silicon oxide and alumina. Organic treatment is implemented to the product which possesses excellent pigment performances.
Main characters
l Excellent whiteness and gloss
l Better hiding power and high tint reducing power
l Better weather, heat and light resistance
l Good dispersiblity in solvent borne system
l Good flowability of dry powder
Quality Standard:Q 3201 NTH 03 (modified ISO591-1:2000)
