Title:
Polyurea, which is particularly useful as an adhesive primer for adhering metals to rubber
Document Type and Number:
Japanese Patent JP6330196
Kind Code:
B2
Abstract:
A polyurea comprises at least urea base units of formula —NH—CO—NH— and additional units. The additional units comprise at least, on the one hand, a secondary alcohol functional group and, on the other hand, an ether, thioether or secondary amine functional group in the alpha position with respect to the secondary alcohol functional group. Such a polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example, glass or metal, to an unsaturated rubber or as corrosion-resistant protective coating for a metal substrate. Metal reinforcers, such as thread, cord, film or plate, coated can also be coated with such a polymer.
