Product Description & Reviews
High temperature one-part alumina-based adhesive for bonding and sealing dense ceramics used in design, process and maintenance applications up to 3000°F (1650°C). Typical applications for Ceramabond 503 include the assembly of dense ceramic components used in ultra high vacuum equipment, repairing of ceramic sager plates used in furnaces, potting thermocouples and gas sensors, and coating platinum/rhodium resistance wires to alumina heater cores.The product must be step cured at 200°F (93°C), 500°F (260°C), and 700°F (372°C) for 2 hours at each temperature. Applied in a thin coat using a brush, spatula or dispenser. Clearance between mating parts at operating temperature should be 2-8 mils (50-200 microns). Blistering may occur if the glue line is too thick or heating too rapid.Ceramabond 503 is inert, chemically resistant material that will not outgas in ultra high vacuum (UHV). It is environmentally safe and non-flammable.
