Abstract
An apparatus and methods for using coatings for metal applications are disclosed. According to one embodiment, an article comprises a cured polymeric film having a first reaction product of a cationic photoinitiator and a compound suitable for cationic polymerization. The article has a second reaction product of a free-radical photoinitiator and a compound suitable for free-radical polymerization; The article has a metal substrate, wherein the cured polymeric film coats the metal substrate.
Claims6
A method, comprising:
- curing a composition having a cationic photoinitiator and a monomer, and a free-radical photoinitiator and a monomer and/or oligomer suitable for free-radical polymerization with ultraviolet radiation forming a UV-cured composition;
- curing with a thermal cure initiator onto a metal substrate, wherein the thermal cure initiator is a blocked isocyanate;
- and
- thermally activating the thermal cure initiator in the UV-cured composition to finalize the forming of the polymeric film.
