Abstract
An article of manufacture and a method are disclosed herein for improving lubricity and wear resistance of a given substrate by applying thereto a composition consisting essentially of low-molecular weight tetrafluoroethylene telomers, an antistatic agent, preferably in the form of a tertiary amine, and a volatile organic solvent, and removing the volatile solvent to produce a thin, dry coating upon said substrate. The compositions herein disclosed have been found to be most effective as preservatives for coating gramophone or phonograph records which provide marked reduction of record groove wear while substantially minimizing noise and harmonic distortion.
