  • Kester 2120 Organic Activated Soldering Flux

    Multiple item options available
    Mfr ID: 2120
    The Kester 2120 is a halide-free, organic flux designed for automated soldering of circuit board assemblies. This flux provides good activity on both bare copper and solder coated boards. The absence of chlorides, bromides, phosphates and highly corrosive materials facilitates removal after soldering. 2120 produces bright, shiny solder joints and high ionic cleanliness after water cleaning. 2120 provides better surface insulation resistance than typical water soluble fluxes, making it particularly suitable for surface mount assemblies.
