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.
A composition for imparting lubricity and wear resistance to a surface having dynamic presentations thereon comprising about 0.001 to about 3.000 weight percent of a composition containing a carboxylate ester, said ester being derived from a perfluoroalkyl alcohol of the formula C.sub.n F.sub.2n+1 (CH.sub.2).sub.m OH wherein n is from about 3 to about 14 and m is 1 to 3 and an aliphatic carboxylic acid having about 3 to 30 carbon atoms, and 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.
A method of treating a surface to render said surface lubricous and wear resistant, which comprises the steps of treating the surface with a solution comprising about 0.001 to about 3.000 weight percent of a composition containing a carboxylate ester derived from a perfluoroalkyl aliphatic alcohol of the formula C.sub.n F.sub.2n+1 (CH.sub.2).sub.m OH wherein n is from about 3 to about 14 and m is 1 to 3 and an aliphatic acid selected from the group consisting of monocarboxylic and polycarboxylic acids said acids having about 3 to 30 carbon atoms, and an antistatic agent selected from the group consisting of amines, fatty quaternary ammonium compounds, fatty esters, phosphate esters and ethoxylated compounds, and about 97.00 to about 99.999 weight percent of a solvent therefor, and removing the solvent therefrom.
A substrate having deposited thereon a composition comprising a carboxylate ester derived from a perfluoroalkyl alcohol of the formula C.sub.n F.sub.2n+1 (CH.sub.2).sub.m OH wherein n is from about 3 to about 14 and m is 1 to 3 and an acid aliphatic selected from the group consisting of monocarboxylic and polycarboxylic acids, and an antistatic agent selected from the group consisting of amines, fatty quaternary ammonium compounds, fatty acid esters, phosphate esters and ethoxylated compounds.
A phonograph record having deposited over the playing surface of said phonograph record a composition comprising a carboxylate ester derived fluoroalkanols having the formula C.sub.n F.sub.2n+1 (CH.sub.2).sub.m OH wherein n is from about 3 to about 14 and m is 1 to 3, and an aliphatic acid selected from the group consisting of monocarboxylic acid and polycarboxylic acids, said acid having about 3 to 30 carbon atoms, and an antistatic agent selected from the group consisting of amines, fatty quaternary ammonium compounds, fatty acid esters, phosphate esters and ethoxylated compounds.
