MIXED MASKED (POLY)ISOCYANATES

摘要

The invention concerns a composition of at least partially masked isocyanates, characterised in that it is masked by at least two different masking agents, selected such that in the octanol test at 110 DEG C, the ratio: D = percentage in equivalents of masking agents unblocking first at 110 DEG C / percentage in equivalents of masking agents unblocking first at 110 DEG C, is greater than 4/3, advantageously greater then 1.5, preferably greater than 2, provided that when a masking agent comprises phenol function as masking function, it does not comprise a COOH function.
