An article of manufacture and a method are disclosed herein for improving lubricity and wear resistance of a given substrate by applying thereto a solution consisting essentially of a dialkanolamine and a halogenated hydrocarbon carrier. The composition herein disclosed has been found to be most effective as preservatives for coating sundry substrates, especially gramophone or phonograph record surfaces whereby there is effected a marked reduction of record groove wear while substantially minimizing noise and harmonic distortion. The preferred composition herein contemplated and disclosed is one consisting essentially of a N-alkyl-substituted N,N-dialkanolamine and a halogenated hydrocarbon carrier, said dialkanolamine having the formula: (HOR.sub.1).sub.2 N--R.sub.2 wherein R.sub.1 is alkylene selected from the group consisting of ethylene, isopropylene and propylene and R.sub.2 is alkyl having four to 20 carbon atoms.
A composition for imparting wear resistance to a surface having dynamic presentations thereon consisting essentially of a solution of an essentially nonvolatile N-alkyl-substituted N,N-dialkanolamine in an amount ranging from about 1.0 to about 0.001 weight percent and a volatile carrier selected from the group consisting of alcohols, ketones, esters, halogenated hydrocarbons and hydrocarbons.
A composition for imparting wear resistance to a surface having dynamic presentations thereon consisting of a solution of an essentially non-volatile N-alkyl-substituted N,N-dialkanolamine in an amount ranging from about 1.0 to about 0.001 weight percent and a volatile carrier selected from the group consisting of alcohol, ketones, esters, halogenated hydrocarbons and hydrocarbons.
A composition for imparting wear resistance to a surface having dynamic presentations thereon consisting essentially of a solution of N-alkyl-substituted N,N-dialkanolamine in an amount ranging from about 1.0 to about 0.001 weight percent in a halogenated hydrocarbon.
A composition for imparting wear resistance to a surface having dynamic presentations thereon consisting of a solution of a N-alkyl-substituted N,N-dialkanolamine in an amount ranging from about 1.0 to about 0.001 weight percent in a halogenated hydrocarbon.
A composition for imparting wear resistance to a surface having dynamic presentations thereon consisting of a solution of from about 1.0 to about 0.001 weight percent N-alkly-substituted N,N-dialkanolamine in a volatile, halogenated aliphatic hydrocarbon having from one to six carbon atoms.
