Dodecanedioic Acid (DDA) Latent Curing Agent

Dodecanedioic Acid (DDA) is a solid dicarboxylic acid used as a latent curing agent for epoxy and TGIC-free powder coating systems, offering excellent storage stability and a smooth, flexible cure at 160–200 °C. When used in combination with epoxy resins, DDA produces powder coatings and adhesives with good flow, high gloss, and improved flexibility versus anhydride-cured systems. Its lower reactivity at room temperature gives outstanding one-component stability.
