Thermoplastic powder coatings were the main material to start with, followed gradually in the 1960s by thermosets: epoxy, epoxy-polyester hybrid, polyester/PRIMID, polyester/TGIC, polyurethane, and acrylate based formulations.
Apart from their excellent surface coating qualities, powder paints have several other advantages as well. First of all they need absolutely no solvents, with or without VOCs. This makes the entire powder coating process clearly superior to other systems with regard to application and utilization efficiency (up to 95%) as well as environmental and energy relevant aspects. Another important advantage is the clearly defined thickness of each coating.
