    摘要: Compositions comprising silicone fluids are formulated to provide improved metal-to-metal lubrication. Such Lubricating compositions comprise a major amount of (1) one or more siloxane polymer (“silicone fluids”) selected from dimethyl siloxane polymers (also known as dimethyl silicone) and/or phenylmethyl dimethyl siloxane copolymers (also known as phenyl silicone), and lesser amounts of (2) synthetic and/or bio-based ester co-fluid, and (3) an alkoxylated aliphatic polyamine derivative. Unexpectedly, the compositions show a significant improvement in metal-to-metal lubrication, performing better than either the silicone fluids alone or and a combination of silicone with-ester and or silicone with-alkoxylated aliphatic polyamine combinations.
