DIRECTIONS: Thoroughly clean the workpiece; breaks should be enlarged to a V-notch. Heat the end of the metal rod with a torch and dip into the flux or sprinkle the flux on the workpiece. At the right temperature, the flux will turn into a liquid that rapidly flows into all cracks and crevices, removing oxides and other impurities. Continue to melt the filler rod until the break or joint is filled, avoiding overheating. It is well to remember that, in brazing, only the filler metal is melted, not the base metal. SÜA Bronze-Flux #2 may also be used as a paste by adding water and mixing well. Brush the paste on the workpiece and also on the brazing rod, allow the paste to dry, and apply heat. Flux residues wash off completely using hot water.

 

SAFETY PRECAUTIONS: SÜA Bronze-Flux #2 contains no fluorides and is reasonably safe to use. Respiratory protection should be worn in heavy dust concentrations. The flux is not absorbed through healthy, intact skin, but is absorbed through burned or wounded skin areas, or if ingested. Absorption or ingestion may cause a pathological disturbance. Brazing should be carried out only in well-ventilated areas.
