Kester 331 is a water soluable formula flux-cored solder wire. More heat stable than most organic fluxes, using this solder wire results in minimal smoke and odor, and can be removed with a water rinse.
Kester 331 organic flux is more effective than rosin fluxes when soldering difficult metals such as copper, nickel and brass. High heat stability allows for minimal smoke and odor. NOTE: Extremely active. Residues may need to be removed after soldering.
