TITLE: Use of liquid cold-setting polyurethane forming components for
corrosion-retardant and wear-protecting coatings of metallic and
plastics surfaces and moulded articles, and of stone and concrete.
European Patent Application EP0081729 A1

ABSTRACT:
Abstract not available for EP0081729
Abstract of corresponding document: US4716210
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).
