RUBBER-METAL BONDING AGENTS Introduction Rubber-Metal Bonding Agents are used to connect dissimilar elastomer (such as natural rubber, styrene, butadiene, chloroprene, acrylonitrile butadiene, butyl ethylene propylene, epichlorohydrin, chlorosulfonated polyethylene, urethane, silicone acryl and fluorrubber) to metal (such as iron, steel, aluminium and brass) or to a wide range of plastics (such as polyamides, polyepoxides, polyoxymethylene and polyfluoroethylene) as well as to glass and textiles. Among the many applications using this bonding method are shock absorbers, motor mounts and vibration mounts, connecting elements, various bearings, O-rings and gaskets, rollers and cylinders, construction elements for rails; tracks and bridge constructions, etc.. Two separate and different methods are used to manufacture the above items:

1. Production of the rubber compound. 2. Priming and bond-coating of the metal parts.

Table 1 (page 2) shows the most important effects of the rubber-metal bond

Pre-Treatment of Metal Parts

s it is well known, in order to assure a corrosion-resistant bond, it is essential to start with a oroughly pre-treated metal surface.

o accomplish this, after cleaning the metal is pre-treated chemically or mechanically. epending on the metal, the parts are degreased in perchloroethylene, trichloroethylene, r 1.1.1. –trichloroethane and subsequently tumbled with carborundum or hard gravel.

hemical pre-treatment is somewhat more complex and again depends upon the metal to be eated.

or plastic surface, a simple cleaning usually suffices: only rarely is a tumbling operation quired. (Polyoxymethylene and polyfluoromethylene must be treated chemically)

ince oxidation may have a negative effect on the bond, the metal should not be stored for ng after tumbling.

herefore, the metal should be primed as soon as possible. In fact, aluminium should be rimed the same day.

, if rubber compounds have been stored for extensive periods, they must be re-omogenized with rollers before bonding.

Although metal parts with the P an be stored for several days in a clean environment, oxidation and migration of plasticizers have a negative effect on the bond. T be reac er, complete remova nt residue is impe ation of gas blis ing the vulcanization pr Although chemical additives generally do not affect bond quality, large proportions of plasticizers and age retardents (such as thioester or thioether) should be avoided.
