Since the powder coated substrate has small molecular substances on its surface, especially on porous substrates such as cast iron, cast aluminum, and zinc substrates, such micronized waxes solve such problems as pores, bubbles and depressions caused by the above substrates coating defects.
Some amino-modified, due to the same type as used in powder coatings, have better wetting in coated fillers and pigments.
Basically, each wax powder has the effect of improving the smoothness of the powder and increasing the storage stability of the paint. Generally, considering the cost, the amount added in the formulation is 0.2-0.5% (wt), and the selected wax powder is more popular. One thing to note is that the production process of low-grade wax and the influence of impurities on the powder coating cannot be ignored.
In addition, the micronized wax can also play a role in controlling gloss, chemical resistance, abrasion resistance, scratch resistance, anti-scratch, etc. in the coating ink. Please also consult the sales staff of Jin Yu International Wax Powder about which kind of micronized wax is suitable.
