摘要： The present invention is directed to a coating composition which includes a component A and component B. Component A is either an emulsion or dispersion having a hydrophobic elastomer stabilized with at lease one emulsifier. Component B is a dispersion or solution of a hydrophilic polymer which is insoluble in water, swellable in water and soluble in one or more water-miscible solvents. The hydrophobic elastomers may be polymers or copolymers of butadiene, isoprene, chloroprene, styrene, acrylonitrile, ethylene, propylene, isobutylene, alkylacrylates and alkylmethacrylates; polyrethanes, polyureas, polysiloxanes, elastomeric polyamides and polyesters. The hydrophilic polymers may be segmented polyurethanes, segmented polyures, segmented polyesters, partially hydrolyzed poly(vinyl acetate), partially hydrolyzed polyacrylonitrile, partially aminolyzed polyacrylonitrile, and ethylene glycol monomethacrylate. An optional Component C may be included which could be organic diluents and plasticizers; surfactants; water-soluble polymeric additives; inorganic or organic salts; pigments; fillers; biocides; UV-absorbers; preservatives; and particulate covalently cross-linked hydrogels.

摘要： 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 A 2) Water-soluble polymer component B 3) Common solvent C for the components A and B The 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.
