                           CALCINED KAOLIN FOR COATING      
(GB(JY)-CK60/90/92)

1. Benefits and Application

The GB-CK series of Kaolin based pigments are produced through delamination, calcination and classification. The well-controlled processes ensure the GB series have no coarse particles and maintains an absolute minimum of 325 mesh residue, so the end user can achieve a high Hegman grind. The GB series pigments also have high brightness, strong hiding powder and superior dispersibility, and it is widely applied in latex paint, powder coating and electrophoresis coating.
Its main benefits are:

It’s the best extender of titanium dioxide with excellent opacity that can
   improve efficiency and cut costs by partly replacing titanium dioxide;
It can easily disperse in water based systems;
It offers superfine particle and with excellent anti-settling property; It is inert to most acids and
   alkaline at ambient temperature and offers good anticorrosive capabilities.
