    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.

    摘要: The disclosed aqueous binder system has a pot life of more than 15 minutes at room temperature and is normally stored as a two-part system. The first part comprises an alkali metal silicate, and the second part comprises a coreactant metal salt of marginal water solubility (at room temperature and neutral pH) which provides reactive divalent metal ions. A rubber latex is normally included in one or both parts, preferably the coreactant (second) part. Preferred coreactants are metal salts of Group II, A or B of the Periodic Table, particularly phosphates, carbonates, or borates of magnesium and zinc. A preferred method of application involves blending the two-part system, spraying it onto a surface, and permitting the sprayed material to cure to a water-resistant layer having a Barcol hardness of at least 10. A low density inorganic filler can be incorporated into the coating to reduce its density below 0.4 g/cc and to provide better insulative properties.
