Patent ID: 8653183

Claim:
A method of curing a coating composition comprising a radical polymerizable compound and an organoborane-amine complex having an organoborane initiator, an amine blocking agent, and water, said method comprising the steps of: A. combining the organoborane-amine complex, the radical polymerizable compound, and water to form the coating composition; B. introducing carbon dioxide into the coating composition or into a composition including at least one of the organoborane-amine complex, the radical polymerizable compound, and water prior to forming the coating composition, wherein the carbon dioxide is present in the coating composition in a molar ratio of at least 500:1 with the amine blocking agent of the organoborane-amine complex to thereby form in situ carbonic acid in a predetermined amount based upon temperature of the coating composition and/or pressure of an atmosphere surrounding the coating composition; C, decomplexing the organoborane-amine complex with the carbonic acid thereby separating the organoborane initiator and the amine blocking agent; and D. polymerizing the radical polymerizable compound using the organoborane initiator in the presence of oxygen.
