摘要:
A method for providing a high-build, low-sag coating by applying an aqueous coating composition including a waterborne polymer, preferably an emulsion polymer, having a glass transition temperature from 0 C. to 70 C., a hydrophobically modified polyurethane thickener, and a coalescent having solubility in water of less than 3 weight % and evaporation rate of at least 0.01(butyl acetate evaporation rate=1.0) to a substrate in a single coat having a thickness of at least 0.05 mm. when dried, and drying, or allowing to dry, the applied coating is provided. The aqueous composition and a curable composition are also provided.
摘要:
A thermosetting powder coating composition having improved optical properties, such as orange peel, gloss and Distinctness of Image (DOI), which includes a reactable mixture of a carboxylic acid group-containing polyester or acrylic, a fatty acid hydroxyalkylamide group-containing material and beta-hydroxyalkylamide curing agent.
摘要:
An aqueous stain-blocking coating composition including an aqueous emulsion copolymer having a glass transition temperature (Tg) from −20° C. to 60° C. and including, as polymerized units, at least one ethylenically unsaturated nonionic monomer and 1.5-6%, by weight based on the dry weight of the copolymer, ethylenically unsaturated strong acid monomer, such as a Phosphorous-containing strong acid monomer, or salts thereof is provided. Also provided is a method for blocking stains by applying the aqueous stain-blocking coating composition to a substrate bearing a stain; and drying, or allowing to dry, the aqueous composition.

摘要:
Aqueous coating compositions containing at least 2 polymer components which provide adhesion and improved durability as measured by improved gloss retention or dirt pick up resistance in dried coatings made from the coating composition are disclosed.
