The introduction of fillers for coatings and their application in coatings.
Time of Update: 2020-09-19
White fill pigment is a mineral material with a fairly low refrengation index, which differs from each other in composition, particle size and granular shape, showing very low masking performance in light and semi-gloss coatings, but giving the coating a "high dry cover" effect (between air/pigment interfaces) on a low-cost basis in flat paint.
