ROYCO® 81MS
SYNTHETIC HIGH TEMPERATURE LUBRICANT
MOLYBDENUM DISULFIDE, SILICONE BASE
GENERAL INFORMATION:
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
Anti-seize protection even when the oil component is removed.

APPLICATIONS:
ROYCO 81MS is designed for use on slow speed sliding metal on metal
surfaces operating at temperatures up to 750oF. ROYCO 81MS may also be
used as an Antiseize compound on threaded parts at temperatures up to
1400oF.

ADVANTAGES:
• Prevents threaded parts from seizing at high temperatures
• Reduces equipment wear
APPROVALS:
ROYCO 81MS meets all requirements of
DOD-L-25681.
LIMITATIONS:
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
antifriction bearings under any circumstances.
