    摘要: A method for reducing the amount of microfoam in a spray-applied clear waterborne thermoset composition is provided. The clear composition comprises an emulsion-polymerized addition polymer or a multi-staged emulsion-polymerized addition polymer with an average particle diameter greater than 120 nanometers and bearing at least two first reactive groups, and a reactive modifier bearing at least two reactive groups. The clear composition is spray-applied to a substrate and cured. Also provided are substrates bearing such spray-applied clear compositions and the emulsion-polymerized addition polymer.

    摘要: An aqueous polymer dispersion containing a predominant amount of first polymer particles and a smaller amount of second polymer particles is provided. The first polymer particles have a glass transition temperature in the range of from -20 °C to 25 °C. The second polymer particles include multiethylenically unsaturated monomer as polymerized units, and have a glass transition temperature of less than 0 °C. The aqueous polymer dispersion is useful for providing dry coatings having improved dirt pickup resistance and an acceptable level of scrub resistance. Also provided is an aqueous coating composition including the aqueous polymer dispersion and a method for preparing a dry coating from the aqueous coating composition.
