New Ceramabond™ 668 Bonds High Temp Ceramics To Metals

Published on 2010-07-14. Author : SpecialChem

Ceramabond™ 668, a new high temperature adhesive developed by Aremco Products, Inc., is now used to bond ceramics to metals used in applications to 2500 °F (1371 °C).


Ceramabond™ 668 is a single part, alumina-silica filled compound, which provides exceptional adhesion to ceramics and metals, and offers a maximum temperature resistance of 2500 - °F (1371 °C). Physical properties include torque strength of 10.6 ft-lbs, dielectric strength of 245 volts per mil at room temperature, and a coefficient of thermal expansion (CTE) of 4.0 ppm/°F (7.2 ppm/°C).

Ceramabond™ 668 is ideal for use with ceramics as well as non-ceramic substrates such as steel and stainless steel. It is applied easily using a brush, syringe or pneumatic dispenser. After application, it dries rapidly at room temperature and cures in 2-4 hours at 200 °F and is resistant to most acids, solvents and fuels. Cleanup of uncured material is accomplished easily with warm water and soap.

Additional applications for Ceramabond™ 668 include bonding and encapsulating small electrical components such as resistors, igniters, temperature probes, and halogen lamps. This product is available from stock in pint, quart, and 1-gallon pails.
