Definitions
- the present invention relates to aqueous uretdione group-containing compositions comprising or consisting of
- At least one hardener containing uretdione groups based on aliphatic, cycloaliphatic, araliphatic and / or aromatic polyisocyanates, which contains no chemically bonded hydrophilizing groups;
- the quantitative ratio of components (A) and (B) is such that the molar ratio of the uretdione present NCO groups of the harder (A) to NCO-reactive groups of the polyol (B) 3: 0.5 to 0 , 5: 3 and wherein A and B are present as a physical mixture.
- the invention relates to a process for producing a polyurethane layer using the aqueous uretdione group-containing composition of the present invention, the polyurethane layer obtained therefrom, and a substrate coated or adhered to this polyurethane layer.
- aqueous coating systems are already available for many applications, they often can not achieve the high quality level of conventional, solvent-borne coatings in terms of resistance to solvents and chemicals or even elasticity and mechanical stress.
- no polyurethane-based coating agents to be processed from an aqueous phase have hitherto become known which sufficiently satisfy the high requirements in practice.
- aqueous uretdione-containing dispersion coatings can be prepared by combining a solid uretdione compound with a molten water-dispersible resin, salting the water-dispersible resin if necessary, and dispersing the resin composition in water.
- the molten water-dispersible resin may have a functionality reactive with the uretdione compound, or the coating composition may contain another water-dispersible resin having a uretdione compound-reactive functionality.
- an epoxy resin was used. It is well known that the epoxy varnishes are inferior in most properties to polyurethane varnishes.
- EP 1687354 A1 it is also necessary for the preparation of these dispersion coatings to use an additional emulsifier, which further impairs the coating properties of the dispersion coatings.
- the production method described in EP 1687354 A1 is associated with a very high thermal load for the uretdione groups, which in practice would most likely lead to a loss of the uretdione groups.
- the dispersions described in EP 1687354 Al were applied immediately after preparation. There is no information in EP 1687354 Al about the stability of these dispersions.
