A new resinous polyol has been described based on a fusion reaction of Epon Resin 829 with Bisphenol A and further esterification with ricinoleic acid. This was based on a modified short oil alkyd cook reaction with unsaturated fatty acids following previously employed techniques. The method was modified by reaction with ricinoleic acid, a 12‐hydroxy oleic acid, the main fatty acid component of castor oil. The resinous polyol derived from this technology is designated Ester 597. Ester 597 was further reacted with a series of urethane prepolymers based on castor oil. A two‐component formula based on this study was used to prepare a two‐can epoxy‐urethane coating system that may have coatings potential as a marine coating and as a maintenance coating for industrial use.
