Urea diisocyanate compositions |
| abstract |
The present invention relates to stable solutions of urea diisocyanates in diisocyanates which are free from urea groups which solutions are prepared by a process which comprises reacting in the absence of a solvent at a temperature from about -20 DEG C to about 80 DEG C an organic diisocyanate with a bis-secondary diamine such that the NCO/NH-ratio is from 2.5 : 1 to 20 : 1. The solutions of the invention are well-suited for use as isocyanate component for the preparation of polyurethane resins by the isocyanate polyaddition process. |
