Abstract
A study was conducted on epoxy urethane paint which is used as the back-side coating of steel sheet coated with polyvinylchloride (PVC) by film lamination method. The addition of melamine to the paint was effective in lowering the curing temperature, but it reduced plasticizer migration resistance and adhesion to the epoxy adhesive. Using oxime as the blocking agent for the isocyanate group and increasing the molecular weight of the epoxy urethane made it possible to lower the curing temperature to 180°C, and resulted in superior properties as back-side coating for PVC coated steel sheet.
