ABSTRACT:
This invention relates to special combinations of polyurethane-urea-forming starting components which are suitable for corrosion-inhibiting wear prevention by casting, centrifugal casting or spraying. Said components are liquid, relatively low viscosity mixtures of polymer-containing or polyadduct-containing polypropylene oxide polyols and/or ethylene oxide-containing polypropylene oxide polyols having a small content of special, low-melting, readily soluble aromatic diamines and tertiary amine catalysts as component (A) which are reacted at room temperature with liquid polyisocyanates based on diphenyl methane diisocyanate or their NCO-prepolymers with polyether polyols as components (B).
