Weld-Sputter-Release BN10
• very good non-wetting and non-sticking of weld sputter
• very good separation efficiency
• perfect protection of substrates and workpieces
• application such as house paint
• ready or use product for standard requirements
• contains "white graphite"


The application of the boron nitride coating of the type Weld-Sputter-Release BN10 enables the easy and fast removing of weld sputter and other splashes which develop during welding and applying wear-protection layers. In this way mechanical working over again of workpieces can be reduced or prevented almost completely. The ready ready for use product Weld-Sputter-Release BN10 can be applied like a commercial wall paint by spraying or brushing, if necessray a dilution with distilled water is possible. As concentrate for highest requirements Weld-Sputter-Release BN25 is available. A quick drying version is the product Boron-Nitride-Coating Grade E on the basis of ethanol.


• The surfaces which can be coated should be clean, dry and free of dust, degrease prior to application.
• Only after long storage time Weld-Sputter-Release BN10 should be shaked or agitated.
• In the as received consistency Weld-Sputter-Release BN10 can be applied by brushing or rolling, if necessary it can be diuted with distilled water.
• In order to achieve even coatings spraying is advantage.
• After the application the coating must be dried carefully, either at air of if necessray with a gas burner.

Storage-Container Size

Weld-Sputter-Release BN10 must be protected against frost. A storage temperature of >5°C (>41°F) is recommended. The containers should be kept closed. Weld-Sputter-Release BN10 is available in 1kg and 6kg-containers.
