<p> THE PRESENT INVENTION DESCRIBES A WATER PROOFED MEMBRANE CURED BY MOISTURE OF A PART THAT INCLUDES A POLYURETHANE POLYMER OBTAINED FROM AT LEAST A POLYETHYL POLYETHER AND AT LEAST A DIISOCIANATE, AND A FORMULA ALDIMINE (I). THE MEMBRANE HAS A LONG STABILITY IN USEFUL LIFE WITH SO MUCH AROMATIC ISOCIANATES, AS ALIFATTICS, A LOW VISCOSITY IN LOW SOLVENT CONTAINMENT, A SUFFICIENTLY LONG OPENING TIME TO ALLOW THE MANUAL APPLICATION AND QUICKLY CURE TO THE MATERIAL TO THE RESISTANCE . THE ALDEHYDE RELEASED IS NON-TOXIC AND LOW FLAMMABILITY AND RAPIDLY EVAPORATES FROM THE MEMBRANE, CAUSING ONLY MINIMUM ODOR EMISSION. THE MEMBRANE HAS HIGH QUALITIES BRIDGES CRACKS IN A WIDE RANGE OF TEMPERATURE AND IS OVERALLY REVIEWED WITHOUT ADHERENCE PROBLEMS BETWEEN LAYERS, WHICH MAKES IT PARTICULARLY SUITABLE FOR ROOFING APPLICATIONS. </p> |
