Ceramast™ 586 Now Used To Assemble High Temp Hepa Filters

Published on 2010-06-04. Author : SpecialChem

Ceramacast™ 586, a new high temperature ceramic adhesive and potting compound developed by Aremco Products, Inc., is now used to assemble high temperature HEPA Filters and a variety of other high temperature components used in applications as high as 2800 °F (1535 °C).

FEATURES

Ceramacast™ 586 is a zirconium-silicate based, phosphate-bonded, chemically-setting ceramic compound ideal for bonding and potting high temperature HEPA filters and electrical components such as infrared heaters, cartridge heaters, gas igniters, halogen lamps, and temperature sensors for applications to 2800 °F (1535 °C). Ceramacast™ 586 exhibits exceptional electrical and mechanical properties. The dielectric strength and volume resistivity are 220 volts/mil and 1011 ohm-cm, respectively. The compressive strength is 8,000 psi and the coefficient of thermal expansion (CTE) is 2.7 (4.9) ppm/°F (°C).

Ceramacast™ 586 is supplied as a powder and is mixed with water to a paste-like consistency in a ratio of 100 parts powder to 14 parts water. It is easily dispensed through pneumatic dispensing equipment and it provides a one-hour pot life and hardening time of 6-8 hours. A full cure is achieved by step curing for 1-2 hours each at 200 °F and 350 °F, respectively. Cured product exhibits a porosity of less than 2% and zero shrinkage. At 1000 °F, the shrink rate is less than 0.3%.

Ceramacast™ 586 is supplied from stock in quart, gallon and five gallon pails. It is one of a series of Ceramacast™ products that have been developed for ultra high temperature electrical assembly applications.
