    • A method of curing a coating composition and a method of forming a cured coating on an automobile component are provided. The coating composition comprises a radical polymerizable compound and an organoborane-amine complex having an organoborane initiator, an amine blocking agent, and water. The method of curing the coating composition comprises the steps of combining the organoborane-amine complex, the radical polymerizable compound, and water to form the coating composition. Carbon dioxide is introduced 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. Carbonic acid is formed in situ within the coating composition through reaction of the water and carbon dioxide. The organoborane-amine complex is decomplexed with the carbonic acid thereby separating the organoborane initiator and the amine blocking agent. The radical polymerizable compound is polymerized using the organoborane initiator in the presence of oxygen.
    • 提供固化涂料组合物的方法和在汽车部件上形成固化涂层的方法。 涂料组合物包含可自由基聚合的化合物和具有有机硼烷引发剂,胺封闭剂和水的有机硼烷 - 胺络合物。 固化涂料组合物的方法包括将有机硼烷 - 胺络合物,可自由基聚合的化合物和水组合以形成涂料组合物的步骤。 在形成涂料组合物之前,将二氧化碳引入涂料组合物或包含至少一种有机硼烷 - 胺络合物,可自由基聚合的化合物和水的组合物。 碳酸通过水和二氧化碳的反应在涂料组合物中原位形成。 有机硼烷 - 胺络合物与碳酸分解,从而分离有机硼烷引发剂和胺封闭剂。 使用有机硼烷引发剂在氧的存在下使自由基聚合性化合物聚合。
