  • Patent number: 8653183
    Abstract: 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.

  • Patent number: 7989070
    Abstract: A coating composition comprises a crosslinkable carbamate-functional resin and an aminoplast. The aminoplast comprises the reaction product of an aldehyde and a melamine. The aminoplast has a content of imino groups of less than or equal to about 10%, a content of alkylol groups of at least about 7%, and a remainder of groups being alkoxyalkyl groups, all based on a total number of reactive sites present in the melamine prior to reaction. A coating system includes a clear coat layer that comprises the reaction product of the crosslinkable carbamate-functional resin and the aminoplast. Threshold adhesion strength, in accordance with MVSS standards, can be achieved between glass and the coating system when the crosslinkable carbamate-functional resin and the specific aminoplast set forth above are reacted to form the clear coat layer, while minimizing problems associated with high viscosity of aminoplasts having a high content of imino groups of greater than 10%.

  • Patent number: 7807743
    Abstract: A coating composition is used to form a clearcoat layer of a film system including a basecoat layer and the clearcoat layer. The coating composition includes a carbamate functional polymer, a cross-linking agent reactive with the carbamate functional polymer, and an acid functional polymer substantially non-reactive with the carbamate functional polymer and the cross-linking agent. The acid functional polymer has an acid value of at least 50 mg KOH/g and contributes to an increased resistance to acid etch of the clearcoat layer. The acid functional polymer also contributes to an increased intercoat adhesion of the basecoat layer and the clearcoat layer thereby decreasing a possibility of separation/delamination of the basecoat layer and the clearcoat layer.

  • Publication number: 20100104769
    Abstract: A technique of treating an automotive coating to modify surface-specific physical properties thereof while retaining bulk physical properties of the automotive coating includes the step of generating a plasma discharge in a plasma generating assembly. The automotive coating is treated with the plasma discharge. The automotive coating is completely cured prior to treatment with the plasma discharge. To treat the automotive coating, either 1) a precursor material is introduced into the plasma discharge to form a thin film on the automotive coating, or 2) the plasma discharge is free of a precursor material and weak bonds are destroyed on or near the surface of the automotive coating.

  • Publication number: 20090023218
    Abstract: The present invention provides a test method for simulating outdoor exposure conditions for testing a coated substrate to evaluate environmental etching of paint caused by acid rain. The test method requires that the test substrate have an acid solution having a pH of less than 6.0 applied thereto by spray or in atomized droplets. The substrate is held in a substantially horizontal position of less than 15° to the horizontal and exposed to heat of above a black panel temperature of 30° C. and light during testing. The light source must emit light in the spectral distribution of at least visible and ultraviolet light, including the spectral distribution of sunlight. Following exposure to testing the substrate is evaluated for environmental etch.
