Ceramacast 584 Quickset High-Temp Potting Compound Now Available
Valley Cottage, NY - September 23, 2005
Ceramacasttm 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).
Ceramacasttm 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 °F (1535 °C).
Ceramacasttm 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/°F (°C).
Ceramacasttm 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 °F and 250 °F, respectively. Cured product exhibits a porosity of less than 6% and shrinkage of less than 4% at 1000 °F.
Ceramacasttm 584 is supplied from stock in quart, gallon and five gallon kits. It is one of a series of Ceramacasttm products that have been developed for ultra high temperature electrical assembly applications.
