Abstract

The present invention provides organometallic latent catalyst compounds, which are suitable as catalysts in polyaddition or polycondensation reactions which are catalysed by a Lewis acid type catalyst, in particular for the crosslinking of a blocked or unblocked isocyanate or isothiocyanate component with a polyol or polythiolto form a polyurethane (PU).
