Custom Rubber To Metal Bonding Parts Manufacturers

In the bonding process of rubber and metal, what are the commonly used surface treatment methods, and how do they improve the bonding strength?

In the rubber-to-metal bonding process, commonly used surface treatment methods include sandblasting, chemical cleaning, phosphating, and coating with adhesives. These methods can significantly improve bond strength as follows:
Sandblasting: Use high-pressure sandblasting to remove the oxide layer, oil stains and other impurities on the metal surface, while increasing the surface roughness. This treatment can improve the mechanical fit between rubber and metal and enhance the bonding strength.
Chemical cleaning: Use specific chemical reagents (such as pickling liquid) to remove contaminants on the metal surface and form a certain activity on the surface to improve the wettability and adhesion of the adhesive.
Phosphating treatment: Forming a stable phosphating film on the metal surface, which can not only prevent metal corrosion, but also provide a better bonding foundation and enhance the bonding effect between the adhesive and the metal.
Coating adhesive: Coating a special rubber-metal adhesive on the metal surface to ensure that the rubber is tightly bonded with the metal during the vulcanization process. This method is the core step in bonding rubber to metal.

When bonding rubber to metal, what are the differences in performance and application areas between different types of adhesives (e.g. phenolic resin, polyurethane)?
