Abstract
The invention relates to cold-curing, low-solvent or solvent-free 2-component polyurethane/polyurea compositions comprising a reaction product of: a) a diamine of the following composition ##STR1## where R is a linear, branched or cyclic alkylene radical having 2-16 carbon atoms which may be optionally substituted by C.sub.1 -C.sub.4 alkyl, wherein in said alkylene radical 1-3 CH.sub.2 groups may optionally be replaced by ##STR2## groups; and b) one or more NCO prepolymers prepared from reaction of one or more linear, branched or cyclic aliphatic isocyanates and one or more branched polyetherpolyols or polyesterpolyols, wherein the NCO prepolymer has an NCO functionality .gtoreq.2; wherein reactants a) and b) are reacted in an NCO:NH equivalent ratio of (1.5-1):1 and their use as coatings and reaction coating materials.
