A primer for vulcanization bonding, comprising an oligomer, the oligomer prepared by copolymerizing an alkoxysilane having an amino group and an alkoxysilane having a vinyl group, and an organometallic compound. This primer for vulcanization bonding provides a metal/rubber composite exhibiting a water resistant adhesion which rivals or is superior to that realized in the use of a coating type chromating agent without the need to subject a metal to hazardous coating type chromate treatment, etc. Therefore, the primer can be effectively utilized in the surface treatment of metals, such as stainless steel, for use in the manufacturing of products comprising a metal and, bonded thereto, a rubber, such as seal products (e.g., oil seal, packings and gasket), valves, damping/vibration control products (e.g., damping steel plate and rubber cushion) and industrial rubber products. |
