Advantages of Calcined Kaolin in Paint Industry

Advantages of Calcined Kaolin in Paint Industry

Better opacity and whiteness make calcined kaolin a great extender for titanium dioxide. The hard calcined kaolin particles help to improve the structural strength of a coating, and also the scrub-resistance of both water and oil-based paints. They also add corrosion-resistance and fire-resistant properties to the paint.

About cost. Calcined kaolin is less than half the price of titanium dioxide. So it is a good option as an extender, particularly in paints above CPVC (critical pigment volume concentration).


Kaolin in the Paint Industry

They are natural minerals on the basis of filling materials. These minerals; most natural state after processing, micritization (shredding), is obtained after separation. In order to obtain or modify certain technical properties, they are insoluble in the medium in which they are applied and are bulk-powdered substances. The industrial minerals used for filling purposes significantly affect the quality and performance of the paint.

At the same time, filling materials reduce the cost of formulation; it also has the advantage of improved film formation, rapid collapse prevention, increased weather resistance and consequently reducing the rate of passage of moisture.

Although it has the advantage of reducing the cost of titanium dioxide, especially in the formulation, it has many similar features.

As IMRI; in the painting industry we are understanding the difference of calcine kaolin as productprice- quality.

The collaboration between one of China’s largest manufacturers of calcined kaolin and IMRI, the market share of high-quality Calcined Kaolin is expanding day by day.
