Patent number: 5688855Abstract: A hydrophilic coating composition used to impart increased lubricity and wettability to the surface of a hydrophobic substrate which is comprised of three essential components:1) Hydrogel-forming polymer component A2) Water-soluble polymer component B3) Common solvent C for the components A and BThe water-insoluble, hydrogel-forming component A consists of a segmented copolymer with long, hydrophilic terminal blocks and the essentially hydrophobic central section. The two polymer components A and B have a limited miscibility in the absence of a common solvent C. Therefore, their blend tends to separate spontaneously into two polymer phases. The phase separation takes place during the solvent evaporation or extraction. A gradient of hydrophilicity and swelling within the coating layer is thus spontaneously created achieving a good adhesion to the substrate and high surface hydrophilicity at the same time.Type: GrantFiled: May 1, 1995Date of Patent: November 18, 1997Assignee: S.K.Y.
