Wax can play a role in the various processes of curing powder coatings. Whether it is extinction or improving the performance of the film, the first time will think of using micronized wax. Of course, different types of micronized wax plays a different role in powder coatings.
The role of wax powder in paint, there are mainly the following aspects:
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.
2. Improve leveling
Some amino-modified, due to the same type as used in powder coatings, have better wetting in coated fillers and pigments.
3. Improve the smoothness of the powder
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 KING HONOR Wax Powder about which kind of micronized wax is suitable.
