ABSTRACT:
Water-soluble or readily water-dispersible fluxes for use in connection with soldering operations in plumbing and related or other environments, particularly for use in connection with the soldering of water lines made from copper or copper-base alloys. The said water-soluble or readily water-dispersible fluxes are produced in the form of pastes in which the paste-forming ingredients are water-soluble surfactants or mixtures of surfactants, especially those of nonionic character, with or without water, but especially where water is present in amounts of at least several percent by weight of the finished flux composition, said paste flux compositions also containing water-soluble amine hydrochlorides, and, advantageously, ammonium chloride, with or without various supplemental ingredients which, when used, are employed in small proportions.
