Radsol 2002SF Flux

Fry Metals "Radsol 2002SF Flux" is an organic acid flux designed for soldering heat exchangers, heater cores and radiators. This high-activity flux produces excellent solder spread on brass, copper and tinned metals with no "greening" of cores. Radsol 2002SF can be applied by spray or dipping; soldering methods with this flux include oven core baking and dip soldering. Radsol fluxes contain no zinc chloride and are non-chelating, reducing heavy metal pickup and thus discharge. 2002SF Flux is typically diluted 2:1 to 5:1 with water depending on the application. This item is a 55 gallon drum.
