In this work, modification and application of Poly (ethylene terephthalate) (PET) waste as organic coating were reported. A potential application of PET coating is to provide protection against corrosion in automobile fuel tanks. PET powder was obtained from post-consumer beverage bottles. The corrosion resistance of the coating was evaluated by total and partial immersion tests in gasoline, diesel oil and alcohol. PET waste was depolymerized in the presence of glycols or ethanol amines and manganese acetate as a catalyst. The produced oligoesters were used to prepare epoxy, alkyd, vinyl ester and polyurethane organic coatings. The cured epoxy, alkyd, polyurethane and unsaturated polyester resins were evaluated as corrosion protective coating application of steel. The recent advances in manipulating patterned recycled PET arrays and patents are reviewed with a focus on the progress of the recycled products and applications.
