Ceramabond 503 High Temperature Ceramic Adhesive

Description

Ceramabond 503, a new high temperature ceramic adhesive formulated by Aremco Products, Inc., is now usedto bond aluminum oxide ceramics for a wide variety of high temperature applications to 3200°F (1760°C).

Ceramabond  503 is an inorganic, water-dispersed, aluminum oxide (alumina) filled adhesive that resists temperatures to 3200°F (1760°C) and is ideal for bonding alumina ceramics. It is applied easily by brush,spatula, or syringe and cures fully in 1-2 hours at 700°F. Mechanical strength continues to improve withincreases in temperature and tensile-shear strength of 900 psi can be achieved by curing further at 1000 °F.Ceramabond  503 is an inert, chemically resistant material that will not outgas in ultra high vacuum (UHV).It is also an exceptional electrical insulator providing a volume resistivity of 109 ohms-cm and dielectric strengthof 250 volts/mil.Typical applications for Ceramabond tm 503 include the assembly of dense ceramic components used in ultra highvacuum equipment, repairing of ceramic sager plates used in furnaces, potting thermocouples and gas sensors, and coating platinum/rhodium resistance wires to alumina heater cores. Ceramabond  503 is available from stock in pint, quart, gallon and five-gallon drums.
