摘要：
Adhesive compositions based on polyurethane and a polyamine suspension have a free isocyanate functional group content of between 2 and 9% by weight, with the polyamine being in the form of particles having a mean diameter of between 30 and 60 &mgr;m. A process for preparing the adhesive compositions involves reacting a polyol and a polyisocyanate to form a polyurethane prepolymer, wherein the prepolymer is mixed with the polyamine suspension. The adhesive compositions can be used for the adhesive bonding of materials, especially for motor vehicles.
