A coating composition includes an aqueous carrier medium, at least a first polymer, and polymeric core-shell particles dispersed in the aqueous carrier medium. The first polymer includes: (i) a barrier segment having aromatic groups and urethane linkages, urea linkages, or a combination thereof; and (ii) an elastomeric segment having a glass transition temperature of less than 0&#xb0; C. The barrier segment can make up at least 30% of the first polymer, based on the total solids weight of the first polymer.

Coating compositions, elastic barrier coatings formed therefrom, and methods of applying such coatings

Provided is a film-forming composition substantially free of organic solvent which includes an aqueous dispersion of polymeric microparticles prepared by emulsion polymerization of a monomeric composition containing (1) at least 10 percent by weight of one or more vinyl aromatic compounds; (2) 0.1 to 10 percent by weight of one or more carboxylic acid functional polymerizable, ethylenically unsaturated monomers; (3) 0 to 10 percent by weight of one or more polymerizable monomers having one or more functional groups capable of reacting to form crosslinks; and (4) one or more polymerizable ethylenically unsaturated monomers. Each of (1), (2), (3) and (4) are different one from the other and at least one of (3) and (4) is present in the monomeric composition. Multi-layer composite coatings and coated substrates also are provided.

Organic solvent-free film-forming compositions, multi-layer composite coatings, and related methods

A curable, aqueous film-forming composition is provided, comprising: wherein Ris linear or branched Cto Calkyl, Ris selected from methyl, linear, cyclic or branched Cto Calkyl, alkenyl, aryl, alkaryl and aralkyl; and 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.

Waterborne thermosetting compositions containing alternating copolymers of isobutylene type monomers

A curable, aqueous film-forming composition is provided that includes a polymeric binder comprising reactive functional groups, a crosslinking agent having at least two functional groups that are reactive with the functional groups of the polymeric binder, and a copolymer flow control agent comprising at least 30 mol % of residues containing alternating residues from a donor monomer and from an acceptor monomer. The copolymer contains at least 15 mol % of an isobutylene type donor monomer. Components (a) and (b) are substantially hydrophobic and are prepared as an aqueous dispersion comprising polymeric microparticles, prepared by mixing components (a) and (b) together under high shear conditions. A multi-component composite coating composition is also provided, comprising a base coat deposited from a pigmented film-forming composition and a transparent topcoat applied over the base coat. The topcoat is deposited from the film-forming composition described above.
