Abstract
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 comprising essentially about 0.001 to about 3.000 weight percent of a composition containing 10 to 100 weight percent of a carboxylate ester, 0 to about 90 weight percent of a tetrafluorethylene telomer, and 0 to about 90 weight percent of an antistatic agent selected from the group consisting of amines, fatty quaternary ammonium compounds, fatty acid esters, phosphate esters and ethoxylated compounds, and about 97.00 to about 99.999 weight percent of a solvent therefor, 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.
