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.
Claims7
A method for production of a resin-composite aluminum profile, comprising the steps of:
- providing an aluminum profile having a coating film applied thereon, said coating film being formed from a coating material capable of forming a functional group which reacts with isocyanate upon treatment by a discharge,
- performing a discharge treatment on a surface of said coating film to form said functional group on said surface to result in a treated surface destined for union with resin capable of reacting with isocyanates, and
- joining a urethane resin substantially formed of isocyanate and polyol to said treated surface.
