Abstract (en)
[origin: EP2130948A1] Pyrophosphate containing bath (I) comprises a reaction product of a secondary monoamine with a diglycidyl ether, where the secondary monoamine is morpholine and the diglycidyl ether is glycerol diglycidyl ether, poly(propyleneglycol)diglycidylether, and/or poly(ethyleneglycol)diglycidylether. Independent claims are included for: (1) the galvanic separation of brightener and copper-tin-alloy coatings comprising contacting a substrate to be coated and an aqueous cyanide free (I) and separating the copper-tin-alloy coating on the substrate; and (2) the reaction product.
