Abstract: | Interest in finding alternatives to TGIC-based powder coatings have driven development of alternate binders for the exterior durable powder coating market. Thermoset powder coatings utilizing carboxylic acid functional polyester resins cured with epoxide-functional acrylate polymers have been evaluated and characterized. Modification of the composition and molecular weight of either component influences the physical properties of formulated powder coating. The behavior of these coatings during the cure process has been investigated and compared with polyester/TGIC systems. 2400 Ellis Rd, Research Triangle Park, NC 27709. |
