High temperature one-part alumina-silica based adhesive. Used to encapsulate electrical devices such as thermocouples, oxygen sensors and resistors, and to produce small ceramic fixtures and parts. Excellent for heaters. Bonds and seals ceramics to ceramics and ceramics to metals in applications up to 2500°F (1371°C).



Ceramabond 668 exhibits a dielectric strength of 118 volts per mil, torque strength of 38 ft-lbs, and coefficient of thermal expansion of 4.0 in/in/°F.



The product must be step cured at 200°F (93°C) for 1-4 hours. Applied in a thin coat using a brush, spatula or dispenser. The clearance between mating parts at operating temperature should be 2-8 mils (50-200 microns). Blistering may occur if the glue line is too thick or heating too rapid. Environmentally safe, non-flammable material, contains no volatile organic compounds.
