Special Formulations
Going a step beyond resin systems, let’s look at how powder coatings can also be grouped based on aesthetic or specific functional capabilities. Additional powder chemistries that serve more niche purposes include non-TGIC polyesters, super-durable polyesters, fluoropolymer powders, GMA acrylics, ultra-low bake and UV powder formulations, fusion-bonded epoxies, chrome-look powders and clear coats.
Polyesters for exterior use crosslinked with hydroxyalkylamide, better known as non-TGIC polyesters, are outdoor-durable polyesters available in a wide range of colors, textures, and glosses. Sold under the name Primid, these materials are used extensively in Europe and other parts of the world, but presently not as much in North America. We may begin to see that change.
Super-durable or premium polyesters are more resistant to UV degradation than standard polyesters. This is primarily due to the improvements in the backbone of the polyester resin. They are available in both TGIC and non-TGIC formulations. In either case, when properly formulated, they can meet stringent weathering performance requirements such as American Architectural Manufacturers Association (AAMA) 2604, a voluntary specification for application on aluminum. Common uses are window and door frames, building structures, and metal railings.
