DuPont Announces Changes to Polyester RAL Product Line

Powder coating transitioned to globally accepted resin system.

DuPont Powder Coatings announces the transition of the DuPont™ Alesta® RAL product line from the standard triglycidyl isocyanurate (TGIC) to hydroxyalkylamide (HAA), TGIC-free chemistry. DuPont Powder, which has more than 20 years of experience in formulating HAAs, 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,1 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. . “The additional benefit is that this chemistry delivers improved performance properties to our valued customers."

According to DuPont, 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
  • Storage stability

DuPont Powder Coatings is one of the world’s leading suppliers of technologically sophisticated powder coatings systems. The business is committed to offer customers innovative coating solutions, which combine optimal corrosion protection with a strong aesthetic appeal.
