Abstract:
Coating compositions containing coalescents and a latex polymer, wherein the coalescent has a volatile organic content of less than about 50% and is dispersible in the coating composition.
Abstract:
The present invention is directed to a coating composition or paint comprising a multistage latex with at least first and second stages, wherein the composition or paint is substantially free of volatile organic compounds (VOC) and capable of film formation even in the absence of coalescent agents. The base paint formulation is capable of being tinted at a point-of-sale (i.e. in-store) using a colorant composition of a type and quantity required to produce a paint of desired color and finish. The paints, including deeply colored paints, show improved block resistance, scrub resistance and tack resistance.
Abstract:
A coating composition is provided that includes (a) a polyester polymer derived by esterifying an aryloxy ether polyol (e.g., an aryloxy ether diol) derived from reaction between a polyhydric phenol or a polyphenol and a non-hydroxyl functional cyclic carbonate, or from reaction between a monophenol and a hydroxyl functional cyclic carbonate; (b) a crosslinker and (c) an optional catalyst.
Abstract:
A pigment grind dispersion contains non-adsorbed titanium dioxide particles dispersed in an aqueous emulsion containing a mixture of (a) water-insoluble film-forming first polymer particles that adsorb to titanium dioxide particles, the first polymer particle amount in the emulsion being less than the saturation level of adsorption when another polymer is not present, (b) water-insoluble film-forming second polymer particles that do not by themselves form composite particles with titanium dioxide particles, the second polymer particle amount in the emulsion being sufficient to inhibit or interfere with adsorption of the first polymer particles to titanium dioxide particles, and (c) extender particles. The pigment grind dispersion has a titanium dioxide pigment volume concentration of about 25 to about 50 and a titania composite ratio of about 32 to about 60.
Abstract:
An interior portion of a container (e.g., a lid portion, a base portion, etc.) includes one or more walls of a body of material (e.g., in a hexagonal configuration, a spiral configuration, a concentric circular configuration, etc.) that define one or more reservoirs. The one or more reservoirs are open to receive fluid composition therein (e.g., when the lid is positioned to close the container).
Abstract:
This invention provides a polymer, which is preferably a polyether polymer. The polymer may be uses in coating compositions. Containers and other articles comprising the polymer and methods of making such containers and other articles are also provided. The invention further provides compositions including the polymer (e.g., powder coatings), which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.
Abstract:
A polymer useful in coating compositions is described. The polymer is preferably an unsaturated polyurethane polymer, which preferably has an iodine value of at least 10. The polymer may be combined with one or more liquid carriers to form a liquid coating composition useful in coating a variety of substrates, including planar metal substrates.
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:
A thermally responsive composition includes a dye and a developer that is free of polyhydric phenols having estrogenic agonist activity greater than or equal to that of bisphenol S. The thermally responsive composition can be used to make BPA-free thermally responsive record materials.
Abstract:
The disclosure relates to a coating method including the steps of providing a multi-component coating composition including two or more components, applying each component to a porous substrate, mixing each component with at least one other component thereby causing at least two components to undergo a chemical reaction.
