    Abstract: Described herein are methods of coating both metallic and polymeric surfaces adding hydrophilicity comprising the steps mixing a coating composition comprising at least one polyol, at least one compound having at least two isocyanate groups, and an organic solvent; introducing nucleophilic functional groups on the surface thereby creating an active surface; subjecting the active surface to the coating composition thereby forming a coated surface; and curing the coated surface. Medical devices, for example, implantable medical devices can be coated by the methods described herein.

    Abstract: Disclosed is a mold-releasing agent comprising, as active ingredients, a graft copolymer (A) in which a polyalkylene glycol or an alkyl ether thereof is graft-copolymerized with a polyfluoro-1-alkene represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)bCH═CH2 (wherein n is an integer of 1 to 6, a is an integer of 1 to 4, and b is an integer of 1 to 3), and a polyfluoroalkylphosphonic acid represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OH)2 (wherein n is an integer of 1 to 6, a is an integer of 1 to 4, and b is an integer of 1 to 3, and c is an integer of 1 to 3) or a salt thereof (B). The mold-releasing agent comprises, as an active ingredient, a compound having a perfluoroalkyl group containing 6 or less carbon atoms, which is said to have low bioaccumulation potential, and having mold release performance equivalent to or more than that of a mold-releasing agent comprising a compound having a perfluoroalkyl group containing 8 or more carbon atoms as an active ingredient.
