A curable, aqueous film-forming composition is provided, comprising: (a) a copolymer containing reactive functional groups and comprising at least 30 mol % of residues having alternating structural units: -[DM-AM]- wherein DM represents a residue from a donor monomer, and AM represents a residue from an acceptor monomer, at least 15 mol % of the copolymer comprising a donor monomer having the structure (I): wherein R1 is linear or branched C1 to C4 alkyl, R2 is selected from methyl, linear, cyclic or branched C1 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl; and (b) a curing agent having functional groups reactive with the reactive functional groups of (a). The invention is also directed to a multi-component composite coating composition including a base coat deposited from a pigmented film-forming composition and a transparent topcoat applied over the base coat. At least one-coat is the film-forming composition described above.
摘要:
A thermosetting composition that includes an ungelled copolymer composition and a crosslinking agent. The ungelled copolymer composition includes a functional group-containing copolymer that includes segments of alternating residues derived from a donor monomer composition comprising an acceptor monomer composition. The donor monomer composition includes one or both of isobutylene and diisobutylene, and the acceptor monomer composition includes acrylic monomers and monomers containing functional groups. The ungelled copolymer composition is substantially free of transition metals and Lewis acids, and the copolymer is substantially free of maleate-type monomer residues and fumarate-type monomer residues. The crosslinking agent has at least two functional groups that are reactive with the functional groups of the copolymer. The thermosetting composition may be in liquid, powder, or dispersed form and may be applied by traditional or electrocoating methods.
摘要:
A process for the production of a coating layer from a coating composition curable with high-energy radiation on a substrate, comprising the successive steps: a) providing a substrate to be coated, b) applying a backing foil coated on one side with an uncured or at least only partially cured coating layer of a coating composition curable by means of high-energy radiation, with its coated side on the entire surface or at least one sub-zone of the surface of the substrate, c) irradiating the entire coating applied in step b) with high-energy radiation, and d) removing the backing foil from the coating which remains on the substrate; wherein irradiation of the coating proceeds through the backing foil and/or after removal of the backing foil.
摘要:
A composition that includes a non-gelled copolymer that includes one or more residues of a first polymerizable ethylenically unsaturated monomer containing a pendant amide, ester or carboxylic acid group. The nearest neighboring monomer residues of the majority of the first monomer residues along the copolymer molecule do not contain pendant carbonyl functional groups. The amide, ester or carboxylic acid group of the residues of the first monomer are the post polymerization transesterification, transamidification or hydrolysis reaction product of a C1-C4 alkyl ester group in the unreacted first monomer with a compound selected from amine functional compounds and hydroxy functional compounds. The reacted copolymer is substantially free of cyclical structures resulting from the transesterification, transamidification or hydrolysis reaction. The compositions may be thermosetting compositions useful in multi-layer composite coatings.
