Abstract: Polyester polyols and polyurethane baking varnishes modified by turpentine were made from condensation reaction and crosslinking.Effects of the ratio of components and the reaction temperature on their properties were discussed.The IR spectra were also studied.By performance testing,it has been confirmed that the varnish possessed good properties and could be used as polyurethane coatings.

Key words: turpentine, polyester polyols, polyurethane coatings
