Product Description
Calcined kaolin is a particularly processed aluminum silicate pigment and multifunctional additive, which is high in brightness, low in impurity and strong in chemical inertia, and easy to disperse in water and oil based structure. It can be used in water and oily paint, putty and sealed pastern. In architectural paint, especially in latex paint, our calcined aluminum silicate products can afford good covering performance as a functional additive. By replacing titanium white partly it could not only lower the costs, but also adjust the luster of the paint. And it can improve the mechanical performance of the paint film, paint 's stability for stock, brushing property. Moreover, it can improve the mechanical properties such as the moisture resistance, impact resilience of the paint, the floatation resistance capacity of the pigment all can be improved.
The Calcined Kaolin GB-CK92 for paint have advantages of high brightness, high opacity and superior dispersibility. They are widely used in latex paint, powder coating and electrophoresis coationg.
Its main benefits are:
The best extender of TiO2.
Dispersing in both water and oil based systems easily.
Good anti corrosiveness.
Excellent opacity.
