Abstract: The thermal barrier composition of the present invention provides a glassy matrix comprising an alkoxy-functionalized siloxane and a functionally-terminated silane or siloxane, polymethylsilsesquioxane dissolved in a crosslinking agent, and optionally a filler and/or hollow glass microspheres.

Abstract: The present invention provides a durable and weatherable hydrophobic coating composition. The hydrophobic coating comprises a glassy matrix formed by crosslinking a silicone or a silane and siloxane, and a fluorinated compound. In one embodiment, the coating composition comprises a glassy matrix and a fluorinated compound, wherein the glassy matrix is formed by crosslinking a mixture of a glycidyl silane modified polyamide, an organic-modified silicone and a C4 to C20 triethoxysilane. In another embodiment, the glassy matrix is formed by crosslinking a silicone and a C4 to C20 silane.

Abstract: A lined ball valve includes a preformed polymeric liner having a flow passage therethrough. The flow passage has a valve stem opening transverse to the flow direction. A ball element with a flow opening therethrough is rotatably mounted in the flow passage. A valve stem is connected to the ball element. A body of fiber-reinforced polymer is molded around the preformed liner. A method for manufacturing a lined valve includes the steps of: (a) injection molding a polymeric preformed liner; (b) supporting the preformed polymeric liner inside a body mold; and (c) compression molding a fiber reinforced resin valve body around the preformed liner.
