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.
