WILMINGTON, DE – DuPont Powder Coatings has transitioned the DuPont™ Alesta® RAL product line from the standard triglycidyl isocyanurate (TGIC) to hydroxyalkylamide (HAA), TGIC-free chemistry. DuPont Powder has over 20 years of experience in formulating HAAs and believes the trend in North America will reflect the transition from TGIC to HAA polyesters already occurring in other regions around the world.
“Responsible Care® issues, relative to the anticipated warning/labeling requirements for TGIC-containing polyesters, are the primary driving force for the alternate technology,” said Megan Wiehe, Product Manager. Responsible Care is the chemical industry’s global initiative that drives continuous improvement in health, safety and environmental performance, together with open and transparent communications with stakeholders. “The additional benefit is that this chemistry delivers improved performance properties to our valued customers,” added Wiehe.
Alesta RAL HAA (TGIC-free) powder products are a more sustainable coating solution, meet or exceed AAMA 2603 specifications, and offer improved performance in weathering, charging (transfer efficiency), cure response and storage stability
