Ceramabondtm 890, a new, ultra high temperature, phosphate-bonded, silicon carbide adhesive
developed by Aremco Products, Inc., is now used to produce high strength bonds in silicon
carbide and nitride-bonded silicon carbide components to 2500 oF (1371 oC). Ceramabondtm 890 is an ultra high temperature, phosphate-bonded, silicon carbide filled, waterbased
formulation that bonds aggressively to silicon carbide and nitride-bonded silicon carbide
products. It is supplied as a single part, dispensable paste that is ideally suited for automatic
dispensing systems.
Ceramabondtm 890 offers exceptional mechanical and thermal properties. Typical properties
include an operating temperature resistance of 2500 oF (1371 oC) and tensile-shear strength of
500-600 psi after exposure to 1000 oF.
Ceramabondtm 890 is applied easily using a hand-tool or automatic dispensing system. A full
cure is accomplished by heating for 2 hours each at 200 oF, 500 oF and 700 oF, respectively.
Shrinkage upon curing is less than 1%. Cleanup of uncured residue is achieved easily using
warm water and soap.
Ceramabondtm 890 is an inert material that exhibits no outgassing upon curing. It also
demonstrates good resistance to moisture and thermal shock.
Ceramabondtm 890 is available from stock in pint, quart, and gallon containers.
