TWO-COMPONENT COATING COMPOSITIONS

摘要

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