POLYUREE USEFUL AS THE PRIMARY OF ADHESION FOR THE BONDING OF METAL HAS RUBBER

摘要

Polyurea type comprising at least one of the base units urea of formula - - - - co — nh — nh and the additional units, characterized in that these additional units comprise at least one hand, a secondary alcohol function, on the other hand, an ether, thioether or secondary amine in the alpha position of the secondary alcohol function. Use of such a polymer such as adhesion primer for the bonding of a substrate, for example glass or metal, with an unsaturated rubber, or as an anticorrosion protective coating of a metal substrate. Metal reinforcement, such as a cord, cable, a film or sheet, coated with a polymer according to the invention.
