Oben Description

Boron-Nitride-Coating Grade E is a secial coating on the basis of boron nitride and ethanol. This coating shows a very good non-wetting behaviour against many metal melts (like Al, Mg, Zn and Pb). Dies, mould, thermocouples, etc. can be coated with Boron-Nitride-Coating Grade E. The outstanding high temperature lubricating qualities enable a good release of castings from moulds and effectively prevent sticking of melts. Short drying times provide a fast and smooth application.


Resuspend or shake Boron-Nitride-Coating Grade E prior to use. Dilute with ethanol if necessary. 
Apply coating on clean surfaces by brushing or spraying. Additional layers may be applied after drying. 
A thin coating application (50-150µm, 2-6 mils) is favourable. With a thick coating application exists the danger of cracking and chipping off.

ObenStorage-Container Size

Keep container tightly closed and store product in a well ventilated and cool place. Boron-Nitride-Coating Grade E is available in containers of 1000ml.

ObenSafety Advices

Boron-Nitride-Coating Grade E contains ethanol (ethyl alcohol) and is labelled highly flammable. Use in well ventilated areas only. An EC material safety data sheet is available.
