BNA Paste
BNA Paste is a non-aqueous-based paste usable in all atmospheres and can be applied as thick layers or brushed like house paint. Yields over 95% BN after heating to 800 C in air. May be used in all atmospheres (air as well as inert or vacuum) to the normal temperature limits of boron nitride ˆ air, 1000-1100 C; vacuum, 1400 C; inert, 1800 C [limited due to sublimation, although higher temperatures have been attained]. BNA PASTE provides highly chemically resistant, thermally-conductive/electrically-insulating Boron Nitride and is suitable for typical areas-of-use of Boron Nitride
