    摘要: A curable composition and process of applying the composition and the resulting composite coatings provide improved resistance to acid etch and mar. The curable composition has (a) about 30 to 90 percent by weight, based on total weight of resin solids, of a film-forming composition selected from the group consisting of: (i) a polyepoxide and a polyacid crosslinking agent; (ii) an acrylosilane polymer, an acrylic polyol polymer, and optionally an alkylated melamine-formaldehyde crosslinking agent; and (iii) a polyisocyanate and a polymer having at least one group that is reactive with isocyanate; and (b) about 10 to 70 percent by weight, based on total weight of resin solids, of a tricarbamoyl triazine compound of the formula: C3N3(NHCOXR)3 wherein X is nitrogen, oxygen, sulfur, phosphorus, or carbon, and R is a lower alkyl group having 1 to 12 carbon atoms, or mixtures of lower alkyl groups. The process involves applying the curable coating as a monocoat on a cured primer surfacer coating on a substrate or as a clear coat on a curable base coat that are cured separately or conjointly. The composite coating includes the primer surfacer and monocoat on a substrate or the color-plus-clear coating on an electrodeposited coating layer or a primer surfacer coating layer.

    摘要: A method of applying a color-plus-clear composite coating to a substrate is provided comprising: applying to the substrate a colored film-forming composition to form a base coat and applying to the base coat a clear film-forming composition to form a transparent top coat over the base coat. Prior to application to the base coat, the clear film-forming composition is heated to a temperature and for a time sufficient to lower its viscosity such that the composition can be atomized and applied as a smooth continuous film. At a temperature of 20-25.degree. C., the clear film-forming composition has a high viscosity such that it cannot be atomized and applied as a smooth continuous film. The clear film-forming composition comprises (1) about 65 to about 85 percent by weight, based on the total weight of resin solids in the clear film-forming composition, of a hydroxyl functional acrylic polymer having a weight average molecular weight of about 5000 to about 25,000 as determined by gel permeation chromatography using a polystyrene standard, and having a glass transition temperature of at least about 10.degree. C.; and (2) about 15 to about 35 percent by weight, based on the total weight of resin solids in the clear film-forming composition, of an aminoplast crosslinking agent.

    摘要: Curable electrocoating compositions and the use of these compositions in a method of electrodeposition are disclosed. The electrocoating compositions comprise an aqueous dispersion of an active hydrogen-containing ionic resin and a capped polyisocyanate in which the polyisocyanate comprises a mixture of a diphenyl-2,4'-diisocyanate, a diphenyl-4,4'-diisocyanate and optionally polyphenyl polyisocyanate in which the diphenyl-2,4'-diisocyanate comprises at least 5 percent by weight of a polyisocyanate mixture. The capped polyisocyanate mixture results in a more stable aqueous dispersion than comparable dispersions prepared with capped polyisocyanates derived from the more common diphenyl-4,4'-diisocyanate and mixtures of diphenyl-4,4'-diisocyanate with polyphenyl polyisocyanate.
