    Abstract: Fiber reinforced resin matrix composite laminates are provided comprising: at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising: at least one barrier layer; and at least one cured adhesive layer derived from high temperature cure adhesive. In some embodiments, barrier layer(s) may be substantially impermeable to organic solvents, water, and/or gasses. In another aspect, fiber reinforced resin matrix composite laminates are provided comprising: a) at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and b) a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising: at least one barrier layer; and at least one electrically conductive layer. In another aspect, a surfacing construction is provided comprising a barrier layer and a curable adhesive layer.

    Abstract: Protective articles are provided which include a fluoropolymer film and an epoxy adhesive, borne on at least one surface of the fluoropolymer film. The Protective articles include multilayer articles comprising a) a fluoroplastic layer, in contact with b) at least one curable adhesive layer, comprising a mixture of an uncured epoxide resin and curative agents selected from the group consisting of dicyandiamide, 4,4-aminophenyl disulfide, guanidine carbonate, thiourea and combinations thereof. Most typically, the curative agent includes dicyandiamide and in some embodiments consists essentially of dicyandiamide.

    Abstract: The invention features a coating composition that comprises a non-urethane acrylate or methacrylate compound in combination with a fluorochemical. Typically, the non-urethane (meth)acrylate is an aliphatic or aromatic (meth)acrylate compound and the fluorochemical typically comprises a monofunctional (per)fluoropolyether (meth)acrylate compound. The coating compositions can provide a protective topcoat layer to a variety of substrates, including wood and vinyl.
