ROYCO 44 is recommended for use as an Antiseize compound for threaded fasteners and fittings as well as spark plugs, igniters, and similar threaded aircraft engine accessory equipment requiring an electrically conductive Antiseize compound or torque aid.

This compound may be safely used in contact with corrosion resistant metals such as austenitic stainless steels, titanium, nickel, and cobalt alloys.

Due to the graphite compound in ROYCO 44, this material should not be used in contact with aluminum, magnesium, cadmium, or zinc alloys and platings without prior evaluation.

Because ROYCO 44 conducts electricity readily, the mating of dissimilar alloys, which may create an electrical potential, should be avoided.
