If your favorite aviation grease can’t take the heat, it's time to upgrade to ROYCO 81MS Synthetic Grease from SkyGeek. The special lubricant is formulated for use in high-temperature environments without seizing, drying or losings its special lubricating properties. The grease is made with microfine molybdenum disulfide and a thermally stable polysiloxane based synthetic oil for better performance in extreme heat. The lubricant has a gray-black color and may be applied via paintbrush, squirt can, or pressure applicator. The grease is naturally self-leveling for a smooth, even coating that protects as it lubricates. The microfine particles of "Moly" adhere and penetrate metal surfaces thereby providing lubrication and Anti-seize protection even when the oil component is removed.

ROYCO high-temperature lubricant from SkyGeek is the perfect choice for all types of aviation applications. The grease goes on easily and offers the features pilots need. Built-in anti-seize additives keep parts moving smoothly and work overtime to decrease maintenance demands by cutting down on friction and other types of wear. This saves time and money, two things any pilot can appreciate. The lubricant is specially designed to stand up to the high-temperature demands of a working engine, making it the smart choice for aircraft mechanics and aviation specialists. It is sold in a convenient 1.75-pound steel can and is resealable after use to help preserve unused portion. The lubricant has a shelf-life from date of manufacture of about four years, so order once today and enjoy the lubricant for years to come. ROYCO 81MS High-Temperature Lubricant is priced competitively and larger orders qualify for special volume pricing. Add a manufacturer's certification to your order for a small additional charge.

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.
