- Formulated for soldering all metals except Stainless Steel and Aluminum.
- Excellent across a broad range of base metals, solders, and temperatures.
- Exhibits excellent capillary action.
Description: Superior No. 22 is a water-based, inorganic-acid flux specially formulated for soldering industrial metals. The flux contains Zinc Chloride, Hydrochloric Acid, and other activators that make this flux active at room temperature where it begins to clean metals and remove oxides. The flux exerts a strong scavenging action to remove oxide coatings and other impurities from the metal surface to produce strong joints. Pre-cleaning is not necessary under most conditions.Applications: Superior No. 22 may be applied with a brush, swab or by dipping. The flux exhibits the best activity between 93-315°C/200-600°F. Post-solder residues are water-soluble, and hot water rinses (60C±10°C/140°F±20°F) may be adequate for most applications. To insure complete removal of flux residues, first use water containing 2% HCl followed by as many hot water rinses as necessary. Information provided by Superior Flux |
