Abstract: An low-temperature curing organic urea hardener(toluene-2, 4-di[N, N-Dimethyl pam-ino propyl urea ] ) for epoxy powder coatings was synthesized. And the production process of epoxy powder coatings was reconstructed, epoxy powder coatings curing rapidly at low curing temperature. the amount of curing agent, the physical and mechanical performances of cured film, the chemical resistance of epoxy pow-der coatings were also studied.
