1. A process for producing a hybrid component, the process comprising joining a metal component to a polyolefin component with a copolyamide-based hotmelt adhesive comprising a copolyamide, a blocked isocyanate, an epoxide, and a functionalized polyolefin, said process not comprising a cathodic electrocoat treatment,
wherein the hotmelt adhesive comprises 2.5% to 15% of the blocked isocyanate and 2.5% to 10% of the epoxide, wherein the hotmelt adhesive comprises 10% to 60% of the functionalized polyolefin, and wherein the functionalized polyolefin is functionalized with at least one acid anhydride moiety.
