<p><P>PROBLEM TO BE SOLVED: To provide adhesives with minimized temperature dependency of shear modulus. <P>SOLUTION: A moisture-reactive adhesive composites which comprise a specific dialdimine and a polyurethane polymer P1 which is liquid at room temperature and contains isocyanate groups. These compositions are notable for a very low temperature dependency of shear modulus, i.e. after 7 days' storage at room temperature and 50% relative humidity, they feature a ratio of the shear modulus measured at -20°C to the shear modulus measured at 23°C of less than 1.7. These adhesive compositions are suitable particularly as glazing adhesives for means of transport. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
