Ceramacasttm 575N, a ceramic based, electrically insulating, high temperature compound, produced by Aremco Products, Inc., is now used to bond ceramic bases to high power lamps used in high wattage lighting applications.
Ceramacasttm 575N is a fine-grain, alumina-filled, ceramic compound ideal for potting high temperature electrical components including lamps, heaters, vacuum feed-thrus, PTC devices, rheostats, and temperature sensors. Material properties include a temperature resistance to 3000 oF (1650 ºC), dielectric strength of 150 Volts/Mil, compressive strength of 11,800 psi, and excellent chemical and moisture resistance.
Ceramacasttm 575N is supplied in powder form and is mixed in a ratio of 100 parts powder to 13-15 parts water. It is easily dispensed thru pressurized dispensing equipment and hydraulically sets in 16 hours at room temperature and cures fully at 250 oF in 1-2 hours. Cured material exhibits a porosity of less than 2% and an extremely low shrink rate of less than 0.3% at 1000 ºF.
Ceramacasttm 575N is available from stock in quart, gallon and five-gallon containers.
