ROYCO 64 is a lithium 12 hydroxy stearate thickened grease formulated with microfine molybdenum disulfide and a thermally stable ester based synthetic oil. Modem additives are utilized to provide high load carrying, rust and oxidation protection, EP performance, and shear stability. Microfine particles of moly adhere and penetrate metal surfaces thereby providing lubrication and antiseize protection even when the oil component is removed or there is a possibility of inadequate lubrication clue to mechanical spreadout of.the lubricant. ROYCO 64 meets all requirements of MIL-G-21164D.
