Abstract
Novel one-component polyurethane systems, to their preparation and use for preparing paints, inks and adhesives. The one-component polyurethane systems include one or more organic and/or inorganic compounds of molybdenum and/or of tungsten in which the molybdenum and/or tungsten has an oxidation state of at least +4.
Claims28
Polyurethane-based one-component baking systems comprising one or more organic and/or inorganic compounds of molybdenum and/or of tungsten in which the molybdenum and/or tungsten has an oxidation state of at least +4.
A polyurethane-based one-component baking systems comprising
- (a) blocked polyisocyanates,
- (b) polymers having polyisocyanate-reactive groups,
- (c) one or more organic and/or inorganic compounds of molybdenum and/or of tungsten in which the molybdenum and/or tungsten has an oxidation state of at least +4,
- (d) water and/or organic solvents or solvent mixtures and
- (e) if desired, further additives and auxiliaries,
- wherein the amounts of (a)+(b) are from 20 to 89.9 parts by weight, (c) is from 0.01 to 5 parts by weight, (d) is from 10 to 70 parts by weight and (e) is from 0 to 10 parts by weight and the sum of the parts by weight of components (a) to (e) is 100.
