Blocking agent-free (uretdione-based) polyurethane powder coating formulations are emission free and thus comply with the highest ecological requirements. Recently found catalysts lead to a dramatically reduced
curing temperature of 120 °C compared to conventional 180 °C.
Currently, Europe consumes more than 350,000 metric tons of powder coating per year. The annual rate worldwide is 1,000,000 metric tons - and rising (Figure 1). By 2008, industry experts anticipate global demand to reach over 1.2 million metric tons, of which Europe will account for 500,000 metric tons.
