Lanxess® Royco® 81MS Silicon Base Synthetic High Temperature Grease 1.75 Lb 81MS1-75LB

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 a paint brush, squirt can, or pressure applicator. The microfine particles of "Moly" adhere to and penetrate metal surfaces, thereby providing lubrication and anti-seize protection on threaded parts at temperatures up to 1400 °F even when the oil component is removed. ROYCO 81MS is designed for use on slow speed sliding metal on metal surfaces operating at temperatures up to 750 °F.

LIMITATIONS
Due to the nature of the product, it is advisable to stir or shake thoroughly before application. The persistence of molybdenum disulfide and the high penetrating properties of 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.
