摘要
The invention relates to dibutyltin oxide preparations and their use for catalysing the crosslinking reactions of cationic lacquer binders which can be crosslinked by transurethanisation and/or transesterification. The dibutyltin oxide preparations contain as the dispersing medium a capped polyisocyanate and/or a curing component bearing activated ester groups. In combination with cationic modified epoxy resins or with cationic acrylate copolymers, the dibutyltin oxide preparations are particularly suitable for the formulation of cathodically depositable, corrosion-resistant primers or light-coloured single coat or covering lacquers.
