Anhydrously curing polyisocyanate-based adhesives

A process for producing an adhesive joint comprising:

• a) applying a coating composition to a surface to form a coated surface, the coating composition comprising:
• a polyisocyanate composition A having an average isocyanate functionality of at least 1.5, and
• at least one catalyst B, which at 23° C. catalyzes a reaction of NCO groups to form isocyanurate groups and/or uretdione groups,
• wherein an isocyanate content of the coating composition is 5% by weight to 60% by weight and a molar ratio of isocyanate groups to isocyanate-reactive groups optionally present in the coating composition is at least 5:1;
• b) contacting the coated surface with a further surface;
• and
• c) curing the coating composition at a temperature of at least 10° C. and at most 60° C.,
• wherein in process step c) initially a temperature between 10° C. and 40° C. is maintained until the adhesive joint reaches a tensile shear strength according to DIN EN 1465 for adhesives of at least 0.5 N/mm2 and then a temperature of at least 50° C. is maintained until the adhesive joint reaches a strength of at least 2 N/mm2.
