Abstract

Process and compositions for producing bondings based on a two component adhesive system comprising PA1 1. an epoxide group-containing prepolymer obtained by reacting a polyether-urethane or a polyester-urethane which contains at least two terminal isocyanate groups with equivalent quantities of glycidol, and PA1 2. a primary amino group-containing polyether or polyamide having at least two primary amino groups, and a molecular weight between 200 and 1800.
