Abstract
A lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, which reduces the coefficient of static friction of said metal surfaces and increases their mobility without adversely affecting the adhesion of paints or lacquers applied thereto. The conditioner is a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and poly-acids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixture thereof.
Claims14
A liquid lubricant and surface conditioner composition for application to aluminum cans consisting essentially of a water-soluble organic material selected from the group consisting of an ethoxylated fatty acid, an alcohol having at least about 4 carbon atoms and containing up to about 20 moles of ethylene oxide per mole of alcohol, and an ethoxylated alkyl alcohol phosphate ester, said composition having a pH of between about 1 and about 6.5.
A process of reducing the coefficient of static friction on the outside surface of a metal can and increasing the mobility of said can, comprising applying to said can a liquid lubricant and surface conditioner composition consisting essentially of a water-soluble organic material selected from the group consisting of an ethoxylated fatty acid, an alcohol having at least about 4 carbon atoms and containing up to about 20 moles of ethylene oxide per mole of alcohol, and an ethoxylated alkyl alcohol phosphate ester, said composition having a pH of between about 1 and about 6.5.
