Abstract
A radiation curable, flexible, paintable composition produced from epoxy compounds and one or more polyol(s) has enhanced durability, thick and thin film adhesion, resistance to mold growth and dimensional changes while reducing solvent emissions. The composition can reduce, if not eliminate, runs and drips during the thermal bake cycles which are associated with using conventional compositions in automotive applications.
Claims20
A method for providing a coating on an automotive body component from a composition comprising a combination comprising at least one epoxy compound, at least one polyol and at least one ultra-violet photoinitiator wherein said method comprises:
- (a) applying the exposed composition onto the automotive body component wherein at least a portion of the automotive body component has a vertical surface, and,
- (b) exposing the automotive body component to a source comprising ultra-violet radiation thereby forming a coating upon the automotive body component.
A method of coating a brake rotor comprising:
- (a) providing a composition comprising a combination comprising at least one epoxy, at least one polyol and at least one ultraviolet photo-initiator,
- (b) applying the composition onto at least a portion of the brake rotor,
- (c) exposing the brake rotor to a source of ultraviolet radiation, and;
- (d) recovering a coated brake rotor.
A method for providing a coating on an automotive body component from a composition comprising a combination comprising at least one epoxy compound, at least one polyol and at least one ultra-violet photoinitiator wherein said method comprises:
- (a) applying the composition onto the automotive body component wherein the automotive body component comprises a weld formed between at least two adjacent components, and,
- (b) exposing the automotive body component to a source comprising ultra-violet radiation thereby forming a coating upon the automotive body component.
