The benefits of several thermoplastic powder coatings

Abstract

Since the development of electrostatic powder spraying, powders based on epoxy resins have been the ones predominantly used. These powders have worked well in many cases and can be used for decorative as well as functional coatings. These coatings due, to the chemical nature of epoxy resins, are ‘thermosetting’. This means they not only undergo a physical change when heated, that causes them to melt and flow but they also undergo a chemical change that causes them to increase in molecular weight or ‘crosslink’. Once this happens they cannot be remelted if heated a second time. Due to the wide use of epoxy powders many people associate powder coating with thermosetting powder.
