What are damping greases?
Damping greases are specialty lubricants. They reduce wear and seal out dust and moisture like tradional greases, but their primary function is to control motion and noise in mechanical and electromechanical devices. For example, the “velvet feel,” silent operation, and the fact that lenses doesn’t coast are all the work of damping greases on the focusing threads of binoculars, zoom lenses, and other optical instruments. The Fluorocarbon Gel 868 damping grease series is a new family of PTFE-thickened damping greases developed by Nye for high-shear, metal-on-metal components that have to operate smoothly and quietly for extended periods.
