New Hi-Temp Cermacast 589 Coating & Potting Compound Now Available
Valley Cottage, NY - December 6, 2002
Ceramacast(TM) 589, a new high temperature, quick-setting ceramic coating and potting compound developed by Aremco Products, Inc., is now available for use in a wide range of applications from the coating of structural steel columns subjected to high temperature oxidation to the potting of small electrical components such as halogen lamps.
Ceramacast(TM) 589 is a two-part, silicon-dioxide based, silicate-bonded, chemically-setting ceramic compound ideal for coating structural steel columns as well as potting small electrical components such as heaters, halogen lamps, gas igniters, and temperature sensors for applications to 2400 °F (1316 °C). Ceramacast(TM) 589 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 5.5 (9.9) in/in/°F (°C) x 10-6.
Ceramacast(TM) 589 is supplied as a two-part system consisting of a powder and liquid binder system. It is mixed to a paste-like consistency in a ratio of 100 parts powder to 35-40 parts binder. It is easily dispensed through pneumatic dispensing equipment and it provides a one-hour pot life and hardening time of 5-6 hours. A full cure is achieved quickly by heat curing for 10-15 minutes at 200°F. Cured product exhibits a porosity of less than 1% and a shrinkage rate of less than .3% shrinkage at 1000°F.
Ceramacast(TM) 589 is supplied from stock in quart, gallon and five gallon pails. It is one of a series of Ceramacast(TM) products that have been developed for use in ultra high temperature coating and potting applications.
