TOUGH AND STRONGLY-ADHERENT ANTI-ICING COATINGS

摘要

A polysiloxane(amide-ureide) which inhibits the ability of ice to adhere to a surface of a physical object when applied to a surface of a substrate. The polysiloxane(amide-ureide) has a backbone including: (i) at least one diamine-terminated polysiloxane of the general formula: wherein, for each unit of the polysiloxane R₁ and R₂ are independently selected from the group consisting of C₁ to C₁₀ alkyls, aryls, and polyaryls; for each unit of the polysiloxane R₃ and R₄ are independently selected from the group consisting of hydrogen, C₁ to C₆ alkyls, aryls, C₃ to C₆ cycloaliphatics, and C₃ to C₆ heterocycles; for each unit of the polysiloxane A₁ and A₂ are independently selected from the group consisting of hydrogen, C₁ to C₆ alkyls, aryls, polyaryls, C₃ to C₆ cycloaliphatics, and C₃ to C₆ heterocycles; for each unit of the polysiloxane, x is a number from 1 to 1000; (ii) at least one aromatic diamine; (iii) at least one diisocyanate; and (iv) at least one halide substituted dicarboxylic acid.
