Lubricant compositions based on PTFE

Use as lubricants having a low friction coefficient and an improved noise reduction among moving mechanical parts of dispersions comprising a fluorinated oil and a (per)fluoropolymer, said compositions dilutable with water and obtainable by mixing:a) a fluorinated oil having a (per)fluoropolyether s...

More Information
Summary:Use as lubricants having a low friction coefficient and an improved noise reduction among moving mechanical parts of dispersions comprising a fluorinated oil and a (per)fluoropolymer, said compositions dilutable with water and obtainable by mixing:a) a fluorinated oil having a (per)fluoropolyether structure,b) a concentrated aqueous dispersion of a (per)fluoropolymer (component b'), stabilized by a non ionic and non fluorinated surfactant,c) a fluorinated and/or hydrogenated surfactant,d) water.
