Abstract A series of polyester polyol resin was synthesized by using 1,4-cyclohexanedimenthanol (1,4-CHDM) and three different diacids: 1,3-cyclohexanedicarboxylic acid (1,3-CHDA), isophthalic acid (IPA) and adipic acid (AA). The solubility and viscosity of the polyester polyols were determined, by using methyl ethyl ketone (MEK). All the polyester polyols were crosslinked with hexamethylene diiscyanate (HDI) isocyanurate to form polyurethane coating films. These films were evaluated for their mechanical and chemical resistance properties. Studies on the film characteristics revealed that the polyurethane films based on cycloaliphatic diacid generally showed comparatively ...
