ROYCO® 1MS

Product Description

MIL-PRF-83483, anti-seize thread and severe duty heavy load compound

Royco® 1MS anti-seize thread compound is a blend of lubrication grade, micro-fine powdered, molybdenum disulfide that conforms to SAE-AMS-M-7866, and technical grade petrolatum conforming to VV-P-236. Royco® 1MS is non-abrasive, highly shear stable, and has a relatively low volatility compared to other thread compounds.

Royco® 1MS meets the requirements of MIL-PRF-83483D.

Royco® 1MS is particularly suitable for use on aircraft engine spark plugs, threaded fasteners and fittings at temperatures below 427°C (800°F). At higher temperatures, Royco® 44 conforming to SAE AMS-2518 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 electrical flow.
