【Description】:
OPA is designed with ultra-high brightness calcined kaolin products, after dehydroxylation by control heat treatment, removal of the combined crystallization hydroxyl molecules, thereby increasing the brightness of the product. The highly micronized process of OPA improved its dispersion properties.

【Application】:
OPA as a calcined kaolin product specially recommended for architectural coatings applied to flat and low gloss, can provide excellent opacity and tinting strength performance. Compared with other similar products, OPA alternative more titanium dioxide and no side effect on paint film performance, the product is easy dispersed in aqueous and solvent based coating system.
