  • Soldering flux
    Publication number: 20020100521
    Abstract: Soldering flux compositions are provided useful for soldering radiators of motor vehicles and heat exchanger assemblies in general. Soldering flux compositions include certain fluorine containing compounds found to reduce the undesirable formation of flux tank precipitates and staining of soldered products. Such soldering flux compositions do not compromise the performance of soldering flux in terms of flux efficiency and high temperature life.
