Polyurethane Powder Coating

Polyurethane powder coatings are similar to their polyester counterparts. Polyurethane is more widely used in the U.S. whereas polyester is predominant in Europe. The principle differences are that polyurethane is harder but less flexible and less impact resistant than polyester. It also has a better flow, the downside of this being worse edge coverage. Polyurethane is more resistant to solvents so most thermoset Antigraffiti powders use this technology. See also Nylon R-AG
