Phillips 66® Gear Shield Synthetic is a viscous, adhesive, transparent synthetic-based gear lubricant with a low viscosity sacrificial diluent for ease of application. It is recommended primarily for the lubrication and cushioning of open and semi-enclosed gears found on stationary equipment, such as ball and rod mills, kilns and paper mills. Gear Shield Synthetic is specially formulated to provide high load-carrying capacity to protect heavily loaded gears from scoring and galling. It forms a heavy, tenacious film that adheres well to metal surfaces and will not harden or flake off at low temperatures. This film has good resistance to water washout and protects the gears against rust and corrosion.
