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.
Claims19
A deep drawn article, comprising:
- a cured polymeric film having a first reaction product of a cationic photoinitiator and (3,4-epoxycyclohexylmethyl) adipate, a second reaction product of a free-radical photoinitiator and a vinyl ether selected from 4-hydroxybutyl vinyl ether and triethyleneglycol divinyl ether, and a third reaction product of a hydroxyl functional monomer and a thermal curing agent;
- and
- a metal substrate, wherein the cured polymeric film coats the metal substrate, and wherein the metal substrate and the cured polymeric film have been deep drawn,
- wherein the bis (3,4-epoxycyclohexylmethyl) adipate is incorporated into the first reaction product in an amount from 30% to 60% by weight based on the total weight of the polymeric film and the vinyl ether is incorporated into the second reaction product in an amount from 5 percent to 30 percent by weight based on the total weight of the polymeric film.
