Abstract: A technical procedure has been described for preparation of powder coating from waste PET resin. It consists of degradation of PET resin in the presence of propylene glycol and glycerin at 533K and ultilization of isocyanato-terminated precursor as latent curing agent. The coating shows a satisfactory result in physical and chemical properties.

Key words: PET resin, powder coating, preparation
