Wax additives play a very important role in the various processes of powder coating curing. Whether it is matting or improving the performance of the coating. Different kinds of waxes play different roles in powder coatings.
Powder coating wax additive role
1, Abrasion and scratch resistance: The wax is distributed on the surface of the coating, prevent scratches and abrasions and provide abrasion resistance.
2, Degassing: wax solves the coating defects such as pores, bubbles and depressions, as the substrate surface of powder coating has small molecules.
3, Improve level: Amino-modified, because it is of the same type as the powder coating, has a better wetting effect in the coating of fillers and pigments, and thus the leveling of the surface is also improved.
4, Control gloss: As in baking, the wax will float to the surface of the coating and form a mist, which plays a role in reducing the effect of gloss.
5, Improve smoothness: Wax powder can improve the smoothness of powder and increase the effect of storage stability of coating.
The role of wax additive in powder coating is increasing, it can affect the rheological performance of the coating, such as degassing, improve the leveling and matting ability, and change the surface state of the coating.
