Abstract
A method is disclosed for producing a resin-composite profile. The method comprises providing an aluminum profile having a coating film that is capable of forming a functional group which reacts with isocyanate. A discharge treatment is performed on the film wherein the treated surface is capable of reacting with isocyanate. A urethane resin substantially formed of isocyanates and polyol is joined to the discharge treated surface.
