Abstract
The instant invention is directed to new liquid bicycloaliphatic triisocyanates and to the use thereof as the isocyanate component in the production of polyurethane plastics by the known isocyanate-polyaddition process. The new triisocyanates are particularly suitable for use as the isocyanate component in low-solvent, light-stable two-component polyurethane lacquers.
Claims5
A composition of matter comprising a triisocyanate corresponding to the following general formula:
- ##STR11## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different each represent a hydrogen atom, a methyl group or the radical --(CH.sub.2).sub.n --NCO, wherein n is an integer of from 1 to 3, wherein two of the radicals R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent --(CH.sub.2).sub.n --NCO, and wherein m = 1 to 2.
