Royco® 64 is a synthetic grease with advanced microfine molybdenum disulfide (MoS2) that meets MIL-G-21164 specifications.
Royco® 64 is a synthetic-based grease formulated for outstanding oxidation and water resistance for applications requiring extreme-pressure (EP) performance. Royco® 64 has a very broad operating temperature range with proven stability in performance between −100°F and 275°F (−73°C and 135°C). Royco® 64 was engineered specifically with added microfine "moly" (MoS2) for heavily loaded sliding surface protection.
These microfine particles adhere and penetrate equipment surfaces and provide long-term protection, even after the oil component is removed via migration or volume loss.
