Abstract

The present invention relates to organic polyisocyanates which have a content of unblocked and blocked isocyanate groups (calculated as NCO) of 5 to 20 wt.%, preferably 7 to 15 wt.%, wherein at least 95%, preferably 100%, of the isocyanate groups are present in blocked form and wherein the blocking agent contains A) 30 to 70 equivalent-% of diisopropylamine, B) 30 to 70 equivalent-% of at least one other blocking agent selected from CH-acidic esters and 1,2,4-triazole and C) 0 to 20 equivalent-% of blocking agents other than those set forth in A) and B), wherein the percentages of A), B) and C) add up to 100.
The present invention also relates to a process for the production of these organic polyisocyanates and their use as crosslinking agents for organic polyhydroxyl compounds in polyurethane coating compositions.
