    • 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.
    • 一件物品包括暴露于沉淀物或气载碎片的耐候性表面; 以及设置在耐候性表面上的耐候性涂层,其中所述涂层包含组分A,一份或两份室温可硫化聚有机硅氧烷组合物; 和组分B,至少一种包含一个或多个硅烷醇或烷氧基 - 甲硅烷基的聚有机硅氧烷的冰释放增强比例,包含约10重量%至约85重量%的至少一个羟基封端或烷氧基封端的聚氧化烯烷基 ; 及其任何反应产物。 在另一个实施方案中,制品包括暴露于沉淀或气载碎片的耐候性表面; 以及设置在耐候性表面上的耐候性涂层,其中所述涂层包括包含树脂聚合物和交联剂的一部分或两部分可加成固化的聚有机硅氧烷组合物,其中所述树脂聚合物和/或交联剂包含冰释放增强比例 共价结合的亲水性官能度,其占涂料组合物的约0.5重量%至约40重量% 及其任何反应产物。
