Ceramacast 586, a new high temperature ceramic potting cement developed by Aremco Products, Inc. (Valley Cottage, NY) is a zirconium-silicate based, phosphate-bonded, chemically-setting ceramic compound ideal for bonding and potting high temperature electrical components including power resistors, infrared heaters, cartridge heaters, gas igniters, halogen lamps and temperature sensors for applications to 2,800 oF. Features include:

  • Exceptional electrical and mechanical properties. The dielectric strength and volume resistivity are 125 volts/mil and 109 ohm-cm, respectively. The compressive strength is 8,000 psi and the coefficient of thermal expansion (CTE) is 2.7 (4.9) ppm/oF. 
  • 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 13-15 parts water by weight. 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 oF and 350 oF, respectively, or setting at room temperature for 24 hours. Cured product exhibits a porosity of less than 2% and zero shrinkage. At 1,000 oF, 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.
