STOP-OFF PAINT FOR:
VACUUM CARBURIZING
Vacucoat 0095 is a newly developed stop-off paint for vacuum carburizing followed by quenching in oil or with pressurized gas. According to the common practice in gas carburizing, Vacucoat 0095 coatings provide safe and exactly defined protection against carbon pickup, thus enabling the following operations such as:
- Cold forming
- Drilling, turning, milling, broaching
- Welding

Characteristics
As the most reliable stop-off paint for vacuum carburizing, Vacucoat 0095 offers major benefits as listed below:
- Easy application by means of brushing, immersion, spraying and or feeding.
- Strong adherence to the steel surface.
- Reliable protection up to case depths of approx. 4 to 5 mm (0.15" to 0.19").
- Extremely low vapor pressure of the coatings ingredients.
- Practically no deposits on the refractories of the furnace.
- Easy removal of residues by washing with hot water or alkaline.
Vacucoat 0095 Instructions For Use:
Application:
The surface areas to be protected must be clean and dry. This means in detail that they must be free of oils and greases, humidity, dust, rust, etc. This is normally achieved by water washing, solvent degreasing or blasting. After thoroughly stirring the contents in the tin, the paint is applied to the surface areas to be protected like an oil paint by brushing, immersion, spraying or feeding. Only one coating of uniform thickness is necessary to provide safe protection.
Drying time normally ranges between 3 and 5 hours, depending on the ambient temperature and humidity. The coating must be thoroughly dry before the coated parts are put into the furnace. Coated pieces should not come into contact with each other, in order to prevent unwanted protection in non-coated areas or, on the other hand, protection defects in the coated areas.
After heat treatment is completed, the residues of the paint can be easily removed from the work pieces by washing with hot water or alkaline, either after quenching in oil (respectively with pressurized gas) or after tempering.
