Extinction powder used in coil coatings

High transparency:

high purity of the product to ensure the refractive index and the index is basically consistent with the resin

High heat resistance:

The special process so that the series of products, will heat quickly spread to other surface paint, prolong the service life of paint.

High suspension:

This series of product within the molecular structure and surface structure of a special processing, long time placement will not appear hard settling and stratification

High extinction:

Advanced production technology not only make the product pore volume increased, high-speed mixer general 10-20M/S line speed, after 10 minutes of stirring.
