New antioxidant and UV absorber deliver performance.
The high performance of powder coatings is further increased by the use of additives. Additives are designed to improve properties such as prevention of discoloration during powder coating resin synthesis and curing, ease of spraying the powder onto the substrate, enhanced durability of the coating during service life through light stabilization, and improved corrosion resistance.
Aside from additives like matting, leveling and degassing agents, other classes of additives are frequently used in powder coatings, such as tribo-charging additives, antioxidants, and light stabilizers. This article discusses the newest laboratory results in this field.
