Calcined kaolin clay GB-CK88B is specially designed for car paint with good extinction performance,high opacity,low density etc.

Benefits and Aplication

         JY-CK is an anhydrous aluminumsilicate produced by a controlled,high-temperature heating of a water-fractionated kaolin.JY-CK is specifically designed for use as a filler in automobile electrophoresis prime coat.As a calcined kaolin pigment,with the property of high brighness,excellent light scattering,fine particle,is  an extender that can replace titanium dioxide partly to improve the efficiency and reduce production costs,and can help paint to form easily the close -grained and smooth paint film.

         It is stable and hard to sedimentate in electrophoresis tank.With low impuriy and good inertia,it can improve paint film's stability against against corrosion and moisture-proof property.The particle has micro platy shape.The series has advantages of low oil absorbency and easy dispersion.

         JY-CK,which is applied in automobile electrophoresis prime coat,supplies excellent deposition stability,paint film flattering ,corrosion resistance,rim angle spreadability and uniformity.Calcined kaolin'sexcellent opacity and adhesion make paint film flatter and denser and get much better stone strikng resistance property.
