ROYCO-1MS (1.75-lb-Tin)

ROYCO 1MS is a blend of lubrication grade micro fine powdered molybdenum disulfide that conforms to Mil-M7866, and technical grade petrolatum conforming to VV-P-236. This compound is non-abrasive, highly shear stable, and has a relatively low volatility compared to some thread compounds. ROYCO 1MS is particularly suitable for use on aircraft engine spark plugs and threaded fasteners and fittings at temperatures below 800°F. At higher temperatures, compound conforming to Mil-T-5544 (ROYCO 44) should be used in lieu of ROYCO 1MS. Since this material is an electrical conductor, it is especially suited for anti-seize applications where the thread compound will not impede the flow an electrical current.
