2125 Soldering Flux
Kester 2125 is a halide-free, organic, acid 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 easy residue removal after soldering. Formula 2125 produces bright, shiny solder joints and good ionic cleanliness after water cleaning. 2125 does not contain any toxic chemicals and is completely biodegradable for environmentally safe disposal of the wash water. 2125 is classified as Type ORH0 under IPC ANSI/J-STD-004 Joint Industry Standard.
