Washed Kaolin for Filler
As a aluminum silicate pigment and multi-functional additive,under products are high in whiteness, low in impurity and strong in chemical inertia. They can be applied in the water coating and the oily paint, putty and sealed gum as it easy to disperse in water and oil system. The products can afford well covering performance, can adjust the sheen of the coating, improve the mechanics properties of the painting film, paint 's stability for stock, brushing property, so they can partly takes place of the titanium dioxide to lower the costs.
