Calcined Kaolin KL-2020

Calcined Kaolin KL-2020


Product Description

Qebui KL-2020 is a pure aluminum silicate with ultra-high brightness and finer particle size. It features excellent opacity, strong tint strength, low residue and easy dispersion.

Application information
Qebui KL-2020 is specially designed for coating industry with ultra-high brightness and particle size distribution. While impacting opacity to coatings, it can improve gloss, brushability and stability of coating, enable non-separation of layers after long storage, therefore preventing flooding and floating problem. It can also enhance film mechanical properties and moist-proof ability as well as impact resistance of coatings system. Qebui KL-2020 plays a role in shielding UV, improving coatings properties like weather fastness, anti-corrosion, heat resistance, acid and alkali resistance, etc.
