Solder paste features a Super Rosin Activated (SRA) flux system for use on oxidized or oily surfaces. The SRA paste also improves wettability on hard-to-solder metals like zinc, Monel(TM), and galvanized steel. The paste also reduces the need to pre-clean parts before soldering and also enhances wetting to provide more reliable solder joints. SRA flux will not tarnish or discolor parts, and residue can be removed with standard rosin cleaning techniques.
