ABSTRACT:
The invention relates to a process for the production of oligourethanes containing terminal mercapto groups by reacting 1-isocyanatomethyl-1,3,3-trimethyl-5-isocyanatocyclohexane with substoichiometric quantities of relatively high molecular weight polyether polyols and mercapto ethanol and to the use of the oligourethanes obtainable in this way as binders for coating and sealing compositions hardenable by oxidation and as additives for epoxide resins.
