Abstract
A process is disclosed to eliminate or diminish oxygen inhibition of the curing of coating resins in the composite industry. A free radical curable coating is applied to a mold surface and an inert gas is used to protect the coatings from oxygen in the air during the cure. The inert gases can be, but are not limited to, nitrogen gas and carbon dioxide gas. The inert gas or mold or both can be heated to a temperature above room temperature.
