Boron-Nitride-Coating Grade E
• high temperature release and lubricating agent
• produces non-wetting surfaces
• for metal melts such as aluminium and magnesium, zinc and lead
• for pressing and high pressure sintering of hard metal powders
• quick drying formulation
• contains "white graphite"

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.

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.

Storage-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.

Safety 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.
