| description | The present invention relates to the use of an aqueous dispersion for production of storage-stable and latently reactive adhesives, wherein the aqueous dispersion contains at least the following dispersed components: (A) at least one semicrystalline or crystalline polyurethane polymer containing carboxyl groups which has a melting temperature in the range of 35 to 80°C, an enthalpy of fusion of ≥ 15 J/g and a partial acid number in the range from 0.8 mg KOH/g to 25 mg KOH/g; (B) at least one polycarbodiimide, at least one polyaziridine and/or a mixture thereof, where the at least one polycarbodiimide and the at least one polyaziridine have a glass transition temperature in the range from -150°C to 30°C; (C) optionally at least one further polymer other than the at least one polymer (A); and (D) optionally at least one additive other than components (A), (B) and (C). In addition, a method of bonding at least two substrates or at least two surface regions of a substrate and an adhesive bond.
La présente invention concerne l'utilisation d'une dispersion aqueuse pour la production d'adhésifs stables au stockage et à réactivité latente, la dispersion aqueuse contenant au moins les composants dispersés suivants : (A) au moins un polymère de polyuréthane semi-cristallin ou cristallin contenant des groupes carboxyle qui a une température de fusion dans la plage de 35 à 80 °C, une enthalpie de fusion ≥ 15 J/g et un indice d'acide partiel dans la plage de 0,8 mg KOH/g à 25 mg KOH/g ; (B) au moins un polycarbodiimide, au moins une polyaziridine et/ou un mélange de ceux-ci, le ou les polycarbodiimides et la ou les polyaziridines ayant une température de transition vitreuse dans la plage de - 150 °C à 30 °C ; (C) éventuellement au moins un autre polymère autre que le ou les polymères (A) ; et (D) éventuellement au moins un additif autre que les composants (A), (B) et (C). De plus, l'invention concerne un procédé de liaison d'au moins deux substrats ou d'au moins deux régions de surface d'un substrat et d'une liaison adhésive. |
