Zusammenfassung:	An article comprises a weatherable surface exposed to precipitation or airborne debris; and a weather resistant coating disposed on the weatherable surface, wherein the coating comprises component A, a one- or two-part room temperature vulcanizable polyorganosiloxane composition; and component B, an ice release-enhancing proportion of at least one polyorganosiloxane comprising one or more silanol or alkoxy-silyl groups and comprising from about 10 weight percent to about 85 weight percent of at least one hydroxy-terminated or alkoxy-terminated polyoxyalkylenealkyl radical; and any reaction products thereof. In another embodiment, an article comprises a weatherable surface exposed to precipitation or airborne debris; and a weather resistant coating disposed on the weatherable surface, wherein the coating includes a one- or two-part addition curable polyorganosiloxane composition comprising a resin polymer and a crosslinker, wherein the resin polymer and/or crosslinker comprises an ice release-enhancing proportion of covalently bound hydrophilic functionality that contributes from about 0.5 weight percent to about 40 weight percent of the coating composition; and any reaction products thereof.
