Abstract
A novel lubricating grease that is useful for underwater applications is made up of lubricating oil that contains a co-polymer of a hydrocarbon backbone for promoting good adhesion and a fluorine containing backbone for promoting lubricity. The grease formulation is resistant to water washout and does not off-gas toxic compounds. In addition to the lubricating oil, the grease formulation includes fumed silica, and may contain one or more corrosion inhibitors, an extreme pressure filler such as boron nitride, and optionally one or more polyurethane initiators.
