Abstract:
A urethane composition useful in a variety of applications such as, for example, as a direct-to-metal coating, i.e. a coating composition that can be applied directly to the surface of a metal substrate without a primer or pretreatment is described. The coating composition preferably includes a polyol that is the reaction product of a resin of general formula (I) with an acid or a diol respectively, with the reaction being carried out in the presence of a catalyst. The coating composition also includes an isocyanate-functional compound as a crosslinker. The coating composition forms a corrosion-resistant film when applied directly to the substrate surface without a pretreatment or primer.
Abstract:
The present invention provides novel packaging articles, e.g., food and beverage cans, having a novel coating composition applied to at least a portion of a surface thereon. In preferred embodiments, the coating composition includes at least a film-forming amount of a copolyester resin having a backbone that includes one or more soft segments and a plurality of hard segments. The copolyester resin preferably has a glass transition temperature from about from about 10° C. to about 50° C. The present invention also provides a method for making coated articles.

Abstract:
A coating composition comprising a blend of one or more polyester resins having a lower average molecular weight and higher melt flow index, where the coating composition is in the form of a powder having particles with a fine particle size distribution, and where the coating composition is configured to form a thin coating (34) that is substantially free of pores.
Abstract:
A polyester-carbamate polymer and coating compositions containing the polymer are provided. The polyester-carbamate polymer preferably includes a polyester-carbamate backbone and one or more blocked isocyanate groups. A coating composition is provided that preferably includes the polyester-carbamate polymer and a thermoplastic dispersion. In a preferred embodiment, the coating composition is an organosol.
Abstract:
A coated fiber cement article in the form of an unattached fiber cement board roofing tile or roofing slate substrate having a first major surface at least a portion of which is covered with a crush resistant final topcoat composition comprising a multistage latex polymer.
Abstract:
A method for making a coating composition by mixing one or more latex polymers and an aliphatic epoxy resin system having an epoxy equivalent weight less than 1000 and being distinct from the one or more latex polymers to provide an aqueous first component, and providing a second component having reactive groups that can react with the one or more epoxy resins. A mixture of the first and second components provides a film-forming curable coating composition that may be used on substrates including cement, cement fiberboard, wood, metal, plastic, ceramic, glass and composites.
Abstract:
Titanium dioxide may be more efficiently used in a coating composition containing a composite pigment particle-forming polymer if during composite formation, the polymer is initially present in a low concentration and the titanium dioxide particles and newly-formed composite particles are dispersed in a waterborne emulsion polymer that does not form such a composite. A pigment grind dispersion of titanium dioxide pigment-polymer composite particles may be made by mixing titanium dioxide particles with the waterborne emulsion polymer. The composite-forming polymer is then added to the waterborne emulsion polymer, or is added independently and concurrently with the titanium dioxide particles. The resulting titanium dioxide pigment-polymer composite particles provide improved coating composition opacity compared to a coating composition that does not contain such composite particles. The coating compositions can contain reduced titanium dioxide amounts and less than a saturation level of the composite-forming polymer.
Abstract:
Membrane-ready fibrous faced gypsum panels, methods, and apparatus are provided. The panels include a first fibrous mat having a first surface and a second surface, a second fibrous mat having a first surface and a second surface, a gypsum core in contact with the second surfaces of the first and second fibrous mats, and a material coating that covers the first surface of the first fibrous mat and forms a substantially smooth outer surface.
