Abstract: A coating composition comprises a urethane resin, a water absorbent polymer, and a curing agent. The urethane resin is obtained by reaction of an isocyanate reactive compound having multi-epoxide functionality and an isocyanate. When applied to a substrate and thermally cured, the coating composition forms a transparent and smooth coating having permanent anti-fog property.

Abstract: Methods and materials are described for preparing organic-inorganic hybrid gel compositions where a sulfur-containing cross-linking agent covalently links the organic and inorganic components. The gel compositions are further dried to provide porous gel compositions and aerogels. The mechanical and thermal properties of the dried gel compositions are also disclosed.

Abstract: The present disclosure provides a coating composition comprising an initiator, a radical curable polyurethane having ethylenically unsaturated functional groups, and a liquid phase, wherein the radical curable polyurethane having ethylenically unsaturated functional groups comprises the reaction products of A) a polyol component; B) a polyisocyanate component; C) an isocyanate-reactive surfactant; and D) isocyanate-reactive component having ethylenically unsaturated functional groups. The resulting cured polyurethane coating resists surface damage by fine particles and has at least washable anti-fog properties, if not permanent anti-fog properties. Articles prepared with a coating according to this invention are also disclosed.

Abstract: A coating composition may include one or more radiation-curable resins having reactive groups in a hydrophilic region, a reactive surfactant comprising a reactive moiety; and a photoinitiator, wherein, upon the exposure of the photoinitiator to light energy, the one or more radiation-curable resins are cured to form a hydrophilic network with the reactive surfactant being bound to the network by binding of the reactive moiety of the surfactant to the reactive groups of the one or more radiation-curable resins. The cured coatings provide long lasting, washable, anti-fog properties.
