摘要：
The invention relates to a coating substance consisting of at least three components as follows: component (I), containing at least one oligomeric or polymeric resin with functional groups that react with isocyanate groups, as a binder (A); component (II), containing at least one polyisocyanate as a cross-linking agent (B); and component (III), containing water. Components (I) and/or (III) contain at least one low molecular and/or oligomeric, essentially unbranched, hydrophobic polyester (C) with at least two hydroxyl groups in the molecule, an OH-number from 56 to 500 mg KOH/g, an acid number ∫10 mg KOH/g and a number average molecular weight Mn of 450 to 2.000 Dalton.
