STOP-OFF PAINTS

Stop-off paints for gas carburising, low pressure carburising, powder and granulate carburising, gas nitriding, nitrocarburising, plasma-/pulse plasma nitriding and annealing processes. 

Carburising and nitriding processes are based on the thermochemical diffusion of carbon and/or nitrogen into the surface layer of heat-treated components.

CONDURSAL, CONDURON and VACUCOAT stop-off paints set standards when high-quality and complex components have to be protected gas-tight against diffusion in defined areas during heat treatment. This is to enable subsequent processing steps, such as machining, forming or welding, in individual cases also to minimise the risk of cracks during truing, especially in the area of thread tips or punctures. The unsurpassed high product quality, based on the use of modern manufacturing and testing methods, provides a process-reliable protection. In addition, the excellent productivity of the stop-off paints enables a particularly economical and resource-saving application.

Application can be carried out by brushing, dipping, spraying, stamping or by customer-specific procedures to suit customer´s requirements. 

We also offer special thinners, adapted to the respective product to ensure the consistency in regard to the customer’s specific need.
