Self-emulsifiable polyisocyanate with high functionality and process for producing the same |
摘要 |
A self-emulsifiable polyisocyanate with high functionality, having the average number of functional groups in 4.3 or more and a viscosity of 8,000 mPa.s (at 25° C.) or less, which is obtained by subjecting a modified polyisocyanate containing allophanate bonds and a poly(oxyalkylene)glycol monoalkyl ether (e) having oxyethylene bonds in a total amount of 30 mole % or more in its molecule to a urethanization reaction, said modified polyisocyanate being obtained by reacting a polyol (a) having the average number of functional groups in an amount of 2 or more with an organic polyisocyanate (b) in the presence of an allophanate-forming catalyst (c) comprising a zirconium carboxylate; and a process for producing the same.
