Luiso – Stop off paints

Upon carburizing- or nitriding processes is it often a request for not to affect certain surfaces or areas of the part to be treated. To avoid such surfaces or areas to uptake carbon or nitrogen during the process, it is possible to apply a so-called stop of paint.

The German manufacturer DAM makes such a stop off paint. The stop off paint is called Lusio and is available into different variants tuned for different hardening depths – for low pressure or gas carburizing as well as for plasma and gaseous nitriding or nitrocarburising processes.

The paint is water based and is therefore easy to apply as well as to rinse-off after the process. The water base makes it also environment friendly.
