    摘要: The invention relates to adhesive compositions based on polyurethane and on a polyamine suspension, characterized in that the free isocyanate functional group content is between 2 and 9% by weight and the polyamine is in the form of particles of mean diameter between 30 and 60 .mu.m. Its subject-matter is also a process for the preparation of the said compositions which consists in reacting a polyol and a polyisocyanate to form a polyurethane prepolymer, which prepolymer is mixed with the polyamine suspension.Such compositions can be employed for the adhesive bonding of materials especially for motor vehicles.

    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.
