¢ñ .Benefits and Application
HA-90T series, as a calcined kaolin pigment, with the property of high brightmess, excellent light scattering, fine particle, is an extender that can replace titanium dioxide partly to improve the efficiency and 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's hard to sedimentate and stable in electrophoresis tank.
With low impurity and good inertia, it can improve paint film's stability against corrosion and moisture-proof property.
The particle has micro platy shape. The series has advantages of low oil absorption and easy dispersion.
HA-90T, which is applied automobile electrophoresis prime coat, supplies excellent deposition stability, paint film flattening, corrosion resistance, rim angle spreadability and uniformity. Calcined kaolin's excellent opacity and adhesion make paint film flatter and denser and get much better stone striking resistance property.
