• Is an inorganic acid-based high strength flux formulated to enable efficient soldering on metals that are typically resistant to wetting by solder.
• The blend of acids used ensures high activity at room temperature where it exerts a quick scavenging action to remove oxides and other impurities, cleaning the metal surface and promoting adhesion of soft solders – typically Sn-Pb or Sn-Zn alloys.
• High Activity Soft Solder Flux produces strong joints and is recommended for use on a variety of ferrous and non-ferrous metals commonly used in plumbing applications, radiator repairs, metalworking, and general industrial soldering.
