Abstract
A method of manufacturing phosphate-free alpha-glycol endcapped resins, and use of the resins in a coating composition, are disclosed. The alpha-glycol endcapped resins are prepared from a linear polymer terminated with phenol end groups and glycidol in the absence of phosphoric acid. The endcapped resins are incorporated into organic solvent-based coating compositions for application to metal substrates.
