Patent ID: 7807744

Claim:
An architectural coating composition consisting of: (i) 0.5-10 percent by weight of a silicone resin based on the total weight of the architectural coating composition, wherein the silicone resin is a DT silicone resin containing 5-60 mole percent of units of the formula R 2 SiO 2/2 and 40-95 mole percent of units of the formula R′SiO 3/2 or a MTQ silicone resin containing units of the formula (R 3 SiO 1/2 ) a , units of the formula (R′SiO 3/2 ) b , and units of the formula (SiO 4/2 ) c , where a has a value of 0.05 to 0.5, b has a value of 0.05 to 0.75, c has a value of 0.05 to 0.6, with the proviso that the value of a +b +c is equal to one, wherein R is an alkyl group containing from one to eight carbon atoms and R′ is propyl; (ii) 10-50 percent by weight of an acrylic resin based on the total weight of the architectural coating composition; (iii) 20 -80 percent by weight of a carrier based on the total weight of the architectural coating composition, the carrier comprising water, a water compatible carrier, or mixtures thereof; (iv) 0.5-40 percent by weight of a pigment based on the total weight of the architectural coating composition; (v) 0.5-10 percent by weight of a surfactant based on the total weight of the architectural coating composition, the surfactant comprising an anionic surfactant, a nonionic surfactant, or mixtures thereof; and optionally (vi) 0-5 percent by weight of an additive based on the total weight of the architectural coating composition, wherein the additive is selected from the group consisting of a thickener, a pigment dispersant, a defoamer, a biocide, and amine compounds.
