Powder coating

Features and Benefits

Because of the pigment affinity group, the dispersion of solid particles is improved and the addition amount of filler and pigment is increased. The flow level (DOI - fresh reflection) is improved. The powder coatings using this additive, especially the HHA system, can obtain better degassing property. Recommended dosage

0.5-2% auxiliary dosage (purchase form) is based on the general formula

The above data are empirical dosage, and good dosage shall be determined through a series of tests.

Addition method and processing guidance

The additive is mixed with resin, curing agent, pigment and other raw materials through a high-speed mixer, and then extruded through an extruder. The good dispersion of the additives by the extruder will help to improve the luster and leveling of the powder coating, and prevent the occurrence of shrinkage cavity, fish eye and granulation.
