| abstract |
The invention relates to two-component coating systems comprising, as component (a), one or more polyisocyanates; as component (b), one or more oligomeric and/or polymeric compounds which can react with component (a); and, as component (c), one or more phosphonates selected from the group of phosphonic acid diesters and diphosphonic acid diesters, wherein (i) component (b) contains all oligomeric and/or polymeric compounds which can react with component (a) and which are contained in the two-component coating system; and (ii) component (b) contains not more than 15% by weight, based on the total weight of component (b) of oligomeric and/or polymeric compounds which carry amino groups that can react with isocyanate. A further object of the invention is a method for the production of the two-component coating systems and the use of said coating systems as a clear coating, particularly for multilayer automobile coatings. |
