A bonding agent coating is a process in which a special layer—also known as a primer or adhesion promoter—is applied to a surface to ensure better adhesion of a subsequent coating. This method is commonly used to create a durable and resilient bond between different materials such as metal and rubber.
GOTEC applies this process, for example, to automotive components where rubber and metal parts must be permanently joined.

GOTEC offers various pre-treatment methods to optimally prepare surfaces for subsequent coating processes. These include degreasing to remove residues and oils, blasting to mechanically roughen the surface, and phosphating, a chemical treatment that enhances corrosion protection and adhesion.
These steps create a clean and active surface on which subsequent coatings can reliably adhere.

Zinc-nickel coating is an electroplating process in which a layer of zinc and nickel is applied to metal components. It provides excellent corrosion resistance and is ideal for parts exposed to harsh environmental or temperature conditions.
GOTEC uses this process especially for metal parts, vulcanization carriers, and rubber-metal components to significantly increase their durability and resistance.

GOTEC manages the entire process—from material procurement and production to delivery.
All procedures are standardized and automated but can be customized to meet individual customer requirements.
This ensures consistent quality, efficiency, and on-time delivery across all production stages.
