Abstract
A substantially particulate-free homogeneous lubricant additive includes a first nonionic fluorochemical surfactant selected from the group consisting of fluoroaliphatic oxyethylene adducts and fluoroaliphatic oxypropylene adducts, and a second oil solubilizing nonionic surfactant and a transport or carrier medium ranging from light oil to grease. The additive also utilizes an antioxidant, a petroleum distillate solvent and a bactericide.
Claims7
A substantially particulate-free homogeneous liquid lubricant comprising:
- between about 0.33 percent and about 0.46 percent by weight of a first surfactant comprising:
- a nonionic fluorochemical surfactant selected from the group consisting of fluoroaliphatic oxyethylene adducts and fluoroaliphatic oxypropylene adducts;
- between about 0.35 and about 0.40 parts by weight of a second surfactant comprising a nonionic surfactant having oil solubilizing capabilities;
- and
- between about 94 percent and about 99.4 percent by weight of a hydrocarbon-based transport medium.
