Heat-curable coating composition for cathodic electrodeposition

摘要

The present invention relates to a heat-curable coating composition, in particular for cathodic electrodeposition coating, containing, (A) from 50 to 95% by weight of a polymerisation, polycondensation or polyaddition product containing functional groups, and (B) from 50 to 5% by weight of a mixture of polymethylenepolyphenyl isocyanates which contains less than 25% of diphenylmethane diisocyanates. n
