Ceramcast™ 584 quickset high-temp potting compound

Ceramacast™ 584, a new high temperature, quick-setting ceramic compound developed by Aremco Products, Inc., is now used to pot heaters and thermocouples and cast small, high strength parts used in applications to 2800 ºF (1535 ºC).

Ceramacast™ 584 is a magnesium oxide based, silica-bonded, quick-setting ceramic compound ideal for potting high temperature electrical components such as cartridge heaters and temperature sensors and casting small high temperature components for applications to 2800 ºF (1535 ºC).

Ceramacastt™ 584 exhibits exceptional electrical and mechanical properties. The dielectric strength and volume resistivity are 100 volts/mil and 109 ohm-cm, respectively. The compressive strength is 4,500 psi and the coefficient of thermal expansion (CTE) is 6.5 (11.7) ppm/ºF (ºC).

Ceramacastt™ 584 is supplied as a kit consisting of the 584-P Powder and 584-L Liquid Binder. It is easily mixed to a paste-like consistency in a ratio of 100 parts powder to 25 parts liquid binder, setting within 5–10 minutes at room temperature. A full cure is achieved by step curing for 2 hours each at 200 ºF and 250 ºF, respectively. Cured product exhibits a porosity of less than 6% and shrinkage of less than 4% at 1000 ºF.

Ceramacastt™ 584 is supplied from stock in quart, gallon and five gallon kits. It is one of a series of Ceramacastt™ products that have been developed for ultra high temperature electrical assembly applications.
