The recycling of post-consumer poly(ethylene terephthalate) (PET) is a worldwide concern due to its environmental impact and large volume of these waste materials produced by society. Current work aims at effective recycling of waste PET from soft drink bottles by glycolysis method and thereby utilization of recycled product for coating application. In the investigation, Ethylene Glycol (EG) was used for glycolysis of PET in presence of 0.5% zinc acetate as transesterification catalyst. PET & EG were taken on molar basis at 1:4 and 1:6. The glycolyzed product was characterized by hydroxyl and acid values, FTIR, 1HNMR spectroscopy. Polyester polyol was successfully synthesized by esterification of glycolyzed product, Adipic acid, Phthalic anhydride and Neopentyl glycol. The produced resin was cured with different polyisocyanate curing agents. The mechanical properties of the cured resins were evaluated. The chemical resistances of cured coatings were evaluated for water, solvents, salt spray, acid and alkali resistance.
