Summary for bonding steel to rubber Discussion
Bonding steel to rubber is discussed as a metal-prep and vulcanizing problem, with the focus on how mild steel can be attached to EPDM or NR rubber. Gary Nelson says the traditional method was brass plating the mild steel before vulcanizing, while noting newer methods may sometimes replace that step. Ertan YAZICI gives a more detailed process: shot-peen the metal, apply a bonding agent such as Parlock, dry it, and then mold-vulcanize the rubber onto the metal; he warns the bonding agent must be applied to a clean surface, not one contaminated by oil during handling. Daniel Cushard suggests contacting Henkel Surface Technologies for a coating that can reduce the number of steps, though the editor cautions against brand comparisons. Overall, the thread points to surface preparation plus a rubber-to-metal bonding agent as the practical route.

A. The traditional way involved brass plating the mild steel before vulcanizing. Whether the newer methods can obviate this requirement in every circumstance, I don’t know.

If the rubber is not yet vulcanized, then you are referring to rubber-to-metal bonding for which there are special bonding agents which are applied similarly to paint. These bonding agents are manufactured by my parent company, as well as Lord Corp and Morton.

A. The best way of rubber-metal adhesion is as follows: – shot-peening of metal – bonding agent (Parlock,..) application on the metal – drying of bonding agent – mould vulcanization of rubber on metal. Be careful that bonding agent is applied to surface not to oil during transporting to the mold.
Good luck.

A. You may want to contact Henkel Surface Technologies. They have developed a coating that reduces the steps for bonding and coating of mild steel and rubber.

Ed. note: Readers, please don’t suggest that one brand is better than other brands as it often leads to a race to the bottom; before you know it we have sales managers posting with fictitious names posing as satisfied customers. Thanks.
