Abstract:
A process for producing an aqueous coating composition comprising an aqueous dispersion of internally cross-linked polymer microgel particles in which the microgel particles are produced by emulsion polymerisation of ethylenically unsaturated monomers including carboxyl functional monomer in an aqueous medium so as to form an aqueous dispersion of carboxyl functional addition polymer followed by reacting this polymer dispersion with a diepoxide resin having an epoxide equivalent weight between 100 and 5000 to form the cross-linked polymer microgel particles.
Abstract:
Described is a curable powder coating composition that provides a durable decorative wrinkle finish after curing, as well as a method of coating a substrate and a substrate so coated. The powder coating composition includes a specific triazine-type amino resin crosslinking agent, a hydroxyl functional resin and an amine blocked non-halogenated sulfonic acid catalyst.
Abstract:
A water-based coating composition and method of making the same is disclosed. The composition includes a halogenated resin, a polyol, a surfactant, and an amine. It is suitable for coating a variety of substrates including polyolefinic substrates such as polypropylene, and operates without aromatic organic solvents.
Abstract:
The present invention provides a curable coating composition that includes at least three components. The coating composition includes a component (a) that includes one or both of a compound (a) (1) having at least one carbamate group or terminal urea group according to the invention and having at least two linking groups that are urethane or urea or a compound (a) (2) having at least two groups selected from carbamate groups, terminal urea groups, or combinations of the two and at least four urethane or urea linking groups. The second component (b) of the coating composition includes a polymer resin comprising active hydrogen-containing functional groups reactive with the third component (c). The resins is selected from polyester, polyurethane, or polyester-polyurethane copolymers. Component (c) of the coating composition is a curing agent that is reactive with the first two components. Preparation of coated articles using the compositions of the invention is also disclosed.
