Reference Notes
? Graphi-Bond™ 551-RN is recommended for reducing atmospheres only. For international
shipments, order two-part system, Graphi-Bond™ 551-RN-X, to extend shelf life.
? This test is performed after curing for 5 hours @ 200 °F.
? Ceramabond™ 690 operates to 1560 °F in an oxidizing atmosphere or to 2700 °F in a vacuum/inert atmosphere.
? Thermal conductivity of monolithic Aluminum Nitride is ~170 W/m-°K (1388 BTU-in/hr-ft2-°F )
? Properties after firing above 700 °F.
? A two-part variation of 835M named 835MB is also available. It is particularly good for bonding ceramics to quartz.
