Abstract:
Two-component coating compositions include: A) a cross-linkable binder compound having at least one functional group reactive towards isocyanate groups, B) a cross-linking agent having at least one free isocyanate group and C) a catalyst component comprising C1) a catalyst for the for the curing reaction between the functional groups of component A) and the isocyanate groups of component B), the catalyst C1) being an organo-metal compound, and C2) an oligomeric or polymeric binder compound having a glass transition temperature Tg of ≧about 20° C., measured by DSC (differential scanning calorimetry) at a heating rate of 10 K/min. The glass transition temperature Tg of the binder compound C2) is above the temperature at which the two-component coating composition is applied, preferably about 10° C. above the temperature at which the two-component coating composition is applied.
