Abstract
Abstract A formulation for the surface treatment of metal articles wherein the article to be treated is immersed and agitated in a working solution of the formulation. The formulation consists essentially of the esterification reaction product of phosphoric acid based upon P 2 O 5 with an alkylphenol of either octylphenoxypoly (ethyleneoxy) ethanol or nonylphenoxypoly (ethyleneoxy) ethanol, and wherein the mol ratio of the reactants ranges from between about 1:3 up to about 3:4 of P 2 O 5 to alkylphenol.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
The method of polishing the surface of a metal article which includes immersing and agitating the article in an aqueous solution comprising: a. the reaction product obtained from the reactant mixture of an alkylphenol selected from the group consisting of an octylphenol having the structural formula: ##SPC7## wherein X represents an integer having an average value of from between about 1 and 30; and a nonylphenol having the structural formula: ##SPC8## wherein Y represents an integer having an average value of from between about 5 and 13; and phosphoric acid based upon P 2 O 5 in a molar ratio of between 1:3 and up to 3:4 of P 2 O 5 to alkylphenol.
Claim 2
Independent Claim
114 words
The method of polishing the surface of a metal article which includes immersing and agitating the article in an aqueous solution comprising: a. the reaction product obtained from the reactant mixture of an alkylphenol selected from the group consisting of an octylphenol having the structural formula: ##SPC7## wherein X represents an integer having an average value of from between about 1 and 30; and a nonylphenol having the structural formula: ##SPC8## wherein Y represents an integer having an average value of from between about 5 and 13; and phosphoric acid based upon P 2 O 5 in a molar ratio of between 1:3 and up to 3:4 of P 2 O 5 to alkylphenol.
