A series of high-reactive powder coating polyesters offering innovative solutions for low-temperature curing or for reduced baking cycle time has been developed, which will allow penetration into new applications. The binders based on these technologies can be cured at peak metal temperatures as low as 130 °C for 10 min, and all of them demonstrated excellent behavior with IR curing as well. This reduction in cure temperatures is bringing a new innovative approach to novel applications and optimized process efficiency while keeping high performance. The objective of this article is to present the findings that demonstrate those achievements.

Allnex powder coating resins R&D’s objective was to support the powder coating market by creating innovative polyester resins that allow the industry to adapt to fast-changing conditions and to:
