New Ceramabond 571 Coats Specialty Catalytic Converter

Ceramabond 571 (Figure 1), a new high- temperature magnesium oxide-based ceramic adhesive manufactured by Aremco Products Inc., is now used to coat specialized catalytic converters used in incineration equipment to 3,2008F (1,760ºC). Ceramabond 571 is a water- based, two-part, fast-set, magnesium oxide filled ceramic adhesive and coating system used in the assembly of high- temperature catalytic converters for applications as high as 3,200ºF (1,760ºC). 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 109Vcm and dielectric strength of 255V/mil. Mechanical properties include tensile shear strength of 500c 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 2008F in 1-2 h. 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, a major advantage and requirement for semiconductor and aerospace applications.
