    摘要： Disclosed is a method for making nongelled addition polymers, especially carbamate functional additional polymers from linear unsaturated anhydrides. The method comprises reacting an unsaturated linear anhydride with an active hydrogen compound to provide two monomers comprising polymerizable C═C bonds, at least one of said monomers comprising an acid functional group; polymerizing the polymerizable C═C bonds of the two monomers to provide an acid functional polymerization product; and reacting the acid functional polymerization product with an epoxy functional compound to provide a nongelled addition polymer, wherein the disclosed method does not include a step comprising the physical removal of any acid functional monomers or polymerization products. Also disclosed is a curable coating composition containing the resulting carbamate functional polymer, as well as a coated substrate comprising a cured film resulting from the application and curing of the disclosed curable coating composition.

    摘要： A coating for improved resistance welding of galvanized steel parts or sheets comprises a binder, and a metal phosphide pigment, preferably a ferrophosphorus pigment, having a particle size of from about 0.1 to about 30 microns. The pigment can also include up to about 40% by weight of an additional metal such as tin, aluminum or lead, which can be combined with the metal phosphide in pigment form or deposited onto the surface of the particles. The coating can be applied to either the faying or non-faying surfaces of the galvanized steel, or to the resistance welding electrode, and may be removed, if desired, after the welding operation.The advantages of the present invention include a significant reduction in welding current and an increase in the weldability lobe width, a restoration of the dynamic resistance beta peak, and an increase in electrode life.

    摘要： A coating system includes a clear coat layer and a sealant. The clear coat layer is formed from a clear coat composition that comprises a crosslinkable carbamate-functional resin and an aminoplast. Optionally, the coating system further includes a sub-clear coat layer. The sealant is bonded to the clear coat layer opposite the sub-clear coat layer. Optionally, the coating system further includes a tie coat layer and that is disposed between the sealant and the clear coat layer. An adhesion promoter is present in the clear coat composition in an amount of less than or equal to about 3% by weight based on the total weight of resin solids of the clear coat composition. Further, the adhesion promoter is present in at least one of the sub-clear coat composition and the tie coat composition in an amount sufficient to increase adhesion between the clear coat layer and the sealant.

    摘要： 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%.

    摘要： A carbamate or terminal urea functional vinyl polymer is prepared by reacting a compound having an hydroxyl group and a carbamate group, terminal urea group, or a group that can be converted to a carbamate or terminal urea group, with a cyclic carboxylic acid anhydride group to form an ester bond and a free acid group from the anhydride; and reacting the free acid group with a compound having an epoxide group. The cyclic carboxylic acid anhydride group may be pendant to a vinyl polymer, or one of the compound having an hydroxyl group, a compound having the cyclic carboxylic acid anhydride group, and the compound having an epoxide group may have polymerizable ethylenic unsaturation that is polymerized, optionally with one or more copolymerizable monomers to form a vinyl polymer. When the compound having an hydroxyl group has a group that can be converted to a carbamate or terminal urea group, the group is converted to the carbamate or terminal urea group after step (a). The carbamate or terminal urea functional vinyl polymer may be included in a coating composition. The coating composition may be applied to a substrate and cured to form a cured coating on the substrate.
