Abstract: The present invention provides two-component instant-set aqueous coating compositions that provide coating films having good film quality despite a rapid film build and set. The compositions comprise, as Component I, a film-forming aqueous anionically stabilized polymer composition, such as an elastomeric acrylic or vinyl polymer, and one or more surfactants; and, as Component II, a polycation tolerant mixture of polycation, an aqueous polymer composition, such as a film-forming acrylic emulsion polymer, and a nonionic or ethoxylated anionic surfactant having an average of 7 or more or, preferably, 9 or more ethylene oxide groups per molecule. Component I can be an elastomeric roof coating composition. The compositions can be co-sprayed to form coatings, e.g. roof coatings.

Abstract: A composition contains the following components: (a) 15 to 49.8 volume-percent of a first polysiloxane that is has a viscosity in a range of 50 centiStokes to 550 Stokes as determined according to ASTM D4283-98; (b) 0.2 to 5 volume-percent of an organoclay; (c) 50-74 volume-percent roundish or crushed thermally conductive fillers including: (i) 5 to 15 volume-percent small thermally conductive fillers having a median particle size in a range of 0.1 to 1.0 micrometers; (ii) 10 to 25 volume-percent medium thermally conductive fillers having a median particle size in a range of 1.1 to 5.0 micrometers; (iii) 25 to 50 volume-percent large thermally conductive fillers having a median particle size in a range of 5.1 to 50 micrometers; and (d) 0 to 5 volume-percent of an alkoxy functional linear polysiloxane different from the first polysiloxane and/or an alkoxy functional linear silane; where volume-percent values are relative to composition volume.
