LOW TEMPERATURE CURING
Powder coatings system for new applications and robust process efficiency

A series of high reactive powder coating Polyesters offering innovative solutions for low
temperature curing or for reduced baking cycle time

Polyesters can be used with four different types ofhardeners including:
Epoxy (Hybrid, Epoxy resins with EEW of 680 to 800 gr/eq)
Hydroxyl-Alkylamide HAA (e.g. Primid XL 552*)
Triglycidylisocyanurate TGIC (e.g. ARALDITE® PT 810*)
Glycidylester (ARALDITE® PT 910 / PT 912*)*Trademarks : Primid® of EMS-Chemie ARALDITE® of Huntsman

Value Proposition
Raise productivity •Save energy •Coat heavy goods •Coat heat-sensitive substrates •Increase production process robustness •The allnex sales range can offer today a wide choice of low bake COOH-Polyesters
Polyesters would allow customers to formulate powders with lower curing-temperatures, this will grant new possibilities
for powder application on heat-sensitive substrates and heavy objects, while also saving energy costs and facilitating thecoating operation.

The over-baking resistance, ie the tendency to yellow (major contribution to DE) of low bake Hybrid-Polyesters remains ata relative stable level with applied cure temperatures. IR-curing results in some instances worse than with convection ovencuring. This can be expected as the energy density of IR is much higher and can easily provoke more yellowing if the energydose is not applied precisely.

The over-baking resistance, ie the tendency to yellowing (major contribution to DE), of low bake HAA-Polyesters remains
comparable at different temperatures. The yellowing of the powders depend to a large extent on the concentration of theHAA in the formulation. IR-curing is with most Polyesters not possible, as the film shows degassing issues due to the release ofH2O. This degassing effect can also be noticed with the high acid-functional resins at 200°C in convection oven.
