The different effects of different treatment methods of extinction powder Dec 07, 2016

For conventional matting powder, it is known that the greater the average particle size of the matting agent, the higher the extinction efficiency. But if the particles are too large, will lead to the film surface is too rough, affecting the feel and appearance.

Select the product with higher porosity (pore volume). The higher the porosity, the higher the powder content per unit weight, and the better the extinction performance.

The smaller the average particle size of matting agent, the better the transparency of the paint film, but the corresponding extinction efficiency will be reduced, it should be pointed out that the fine powder content is too high, the transparency will have a negative impact.
