Polyisocyanates with biuret structure, blocked with secondary amines |
| abstract |
The present invention provides a 5 to 45 equivalent percent biuret group of formula (1) based on the sum of free NCO groups and blocked NCO groups in the final product of at least one polyisocyanate and at least one biuretizing agent and optionally a catalyst React; Optionally, the resulting burette polyisocyanate is further reacted with the aid of an isocyanate-reactive compound and / or catalyst to further modify the free NCO groups; Storage prepared by blocking at least 95 mol% of the remaining free NCO groups with a blocking agent of formula R 1 R 2 NH, wherein R 1 and R 2 are independently of each other an aliphatic or cycloaliphatic C 1 to C 12 alkyl radical It relates to a stable blocked polyisocyanate.n n n <Formula 1>n n n n n n n n This blocked polyisocyanate can be used to prepare coating compositions that can be used to coat polyurethane polymers and substrates. |
