Bayer Corp. has developed new diethyl malonate (DEM)-blocked isocyanate crosslinkers that enable a significant reduction in the curing temperature of powder coatings. DEM-blocked isocyanates have additional applications in wood and plastic coatings as well. Advantages of using these crosslinkers are lower curing temperature for powder coatings and greater productivity in the coating process, according to the company. The new crosslinker can be easily incorporated into conventional hybrid or TGIC powder coating formulations as a fortifier.
