Original Press Release:
Ceramabond 571 Bonds Thermocouples to High Temperature Heater
Ceramabond™ 571, a new high temperature magnesium oxide based ceramic adhesive manufactured by Aremco Products, Inc., is now used to bond thermocouples to high temperature molybdenum-rhenium heater tubes for applications to 3200o F (1760 ºC).
Ceramabond™ 571 is a water-based, two-part, fast-set, magnesium oxide filled ceramic adhesive and coating used in the assembly of high temperature catalytic converters for applications as high as 3200o F and (1760 ºC).
Ceramabond™ 571 is ideal for assembling and insulating ceramic and metal components used in high temperature devices. It demonstrates exceptional electrical properties including a volume resistivity of 109 ohm-cm and dielectric strength of 255 volts per mil. Mechanical properties include tensile shear strength of 500 psi and torque strength of 21.6 ft-lbs.
Ceramabond™ 571 is a two-part, easy to mix, powder and liquid system. Mixed in a ratio of 1.5 parts powder to 1.0 parts liquid by weight, the adhesive sets at room temperature and is cured rapidly at 200o F in 1-2 hours. It is easily dispensed and uncured material cleans up quickly with warm water.
Ceramabond™ 571 is a completely inorganic system containing no volatile organic compounds. It will not outgas in ultra high vacuum (UHV), a major advantage and requirement for semiconductor and aerospace applications. Applications for include the attachment of temperature probes and the fabrication of heaters, igniters, high power resistors, gas chromatographs, mass spectrometers, and oxygen analyzers.
