ROYCO 81MS is a high temperature semi-fluid lubricant formulated with microfine molybdenum disulfide and a thermally stable polysiloxane based synthetic oil. This gray-black mixture may be applied via paint brush, squirt can, or pressure applicator. The microfine particles of "Moly" adhere and penetrate metal surfaces thereby providing lubrication and Antiseize protection even when the oil component is removed.

Shelf-Life From Date of Manufacture: 4 Years

NATO Stock #: S-1735
Royco 81MS is designed for use on slow speed sliding metal on metal surfaces operating at temperatures up to 750°F. Royco 81MS may also be used as an Antiseize compound on threaded parts at temperatures up to 1400°F.
Due to the nature of the product, it is advisable to stir or shake thoroughly before application. The persistence of the molybdenum disulfide and the high penetrating properties of the synthetic base oil make this material difficult to remove from surfaces. The material may also stain yellow metals a darker color. ROYCO 81MS should not be used on anti-friction bearings under any circumstances.
