Stop-Off metal surface coatings

Control and stop the surface hardening of ferrous metals

ATP Metseal coatings are an advanced group of water-based metal surface coatings designed to manage the surface hardening of ferrous metals during heat treatments. This technology represents an efficient and economical method to preserve selected surfaces during the cementation process. Their main function is to regulate the diffusion of gases, both inside and outside the metals, offering excellent protection.

Thanks to Metseal metal surface coatings, a sort of defensive barrier is created during heat treatment, reducing or eliminating the need for wasteful procedures such as copper plating. These coatings, therefore, not only limit the diffusion of gases, but are transformed into a tailor-made protective mask, adapting to the specific needs of the hot working process.

Depending on the type of surface coating, the following types of reactions can be stopped:

However, our company is also committed to formulating customized metal surface coating solutions, tailor-made to meet the different needs of industrial processes. We are ready to support your hot working operations with highly adaptable and targeted solutions.

What are the methods of application of Metseal metal surface coatings?

Metseal metal surface coatings offer multiple application modes, allowing total flexibility in the process of protecting metal surfaces. You can choose between techniques such as brush application which allows precise control over specific areas or dip mode, which adapts perfectly to components of various sizes, ensuring uniform coverage across the entire surface.

Spray application offers speed and efficiency while the floating mode allows the coating to be distributed in a similar way to a fine rain or mist on the metal surface. This variety of application options allows you to adapt the surface protection strategy to the specific needs of each industrial process, ensuring optimal and long-lasting results.
