More Information
Summary:Two-component coating system, based on polyurethane, preferably comprises: (a) polyisocyanate, which is optionally hydrophilic; (b) compound having a group reactive with isocyanate, optionally hydrophilic in water and optionally in the presence of organic solvents or solvent mixtures; (c) alkali metal salts of phosphomolybdic acid; and (d) optionally further additives and auxiliaries. The sum of (a) and (b) is 20-99.9999 parts by weight. The amount of (c) is 0.0001-5 parts by weight and (d) is 0-75 parts by weight. The sum of (a) to (d) is 100 parts by weight. Independent claims are also included for: (1) producing the coating system, comprising introducing the component (c) during the preparation of the component (a) or (b) respectively; and (2) a substrate, which is coated, sealed or bonded with the system.
