Catalyst compound for two-component coating compositions

A method for applying a two-component coating composition containing a catalyst compound to a substrate, the method comprising the steps of:

• preparing an 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 (“binder compound II)”) in an organic medium by forming an organic solution or dispersion of the binder compound II) in one or more organic solvents;
• mixing the organic solution or dispersion of the binder compound II) with an organo-metal catalyst for a curing reaction between isocyanate groups and functional groups reactive towards isocyanate groups (“catalyst I)”);
• converting the mixture of catalyst I) and binder compound II) into an aqueous phase, wherein the binder compound II) is neutralized prior to or during the conversion into the aqueous phase;
• applying the aqueous phase to a substrate;
• and
• drying and curing the aqueous phase.
