摘要: There is provided a coating composition comprising: (a) a one part moisture cure polyurethane comprising: an aromatic polyurethane prepolymer having backbone derived from polyether and at least one aromatic end group, wherein the coating composition comprises about 8 wt % to 90 wt % polyurethane prepolymer based on the total weight of the coating composition; (b) 2 to 60 wt % of an inorganic filler based on the total weight of the coating composition; and (c) 2 to 60 wt % of a solvent based on the total weight of the coating composition, wherein the coating composition, when cured, is a water-vapor semi-permeable, air and water barrier film. There is also provided a cured coating composition and articles made therefrom.

摘要: Provided are reactive compositions for making a polyurethane-based rain-erosion protective coating for rotor blades, the reactive composition comprising an isocyanate-reactive component and an isocyanate-functional component and wherein the isocyanate-reactive component comprises a first component i) being a short chain hydroxyl-functional compound having two terminal (α-ω) hydroxyl groups, a molecular weight of less than 250 g/mole and containing at least 2 carbon atoms and a second component ii) comprising a high molecular weight hydroxyl-functional compound having two terminal (α-ω) hydroxyl groups and a molecular weight of at least 250 g/mol and comprising one or more units selected from oxyalkylene units and polyoxyalkylene units and wherein the isocyanate-functional component is an isocyanate prepolymer of the general formula NCO—Z—NCO, wherein Z is a linking group comprising at least two urethane (—NH—CO—O—) units and additionally one or more units selected from alkylenes, oxyalkylenes, polyoxyalkylenes, alkylene esters, oxyalkylene esters, polyoxyalkylene esters and combinations thereof. Also provided are protective coatings obtained from the reactive compositions and methods of applying the coatings to articles.
