- Low organic content.
- Completely free of zinc and chlorides.
- High fluxing activity.
- Residues are completely water-soluble.
Description: Superior No. 515 is a water-based, water-soluble flux with extended temperature capability that begins to clean metals at room temperature. This inorganic flux is chloride-free and reaches peak activity at 260°C/500°F. Residues are non-hygroscopic and non-corrosive and will wash-off with water. Superior No. 515 is specially formulated for soldering radiators and industrial soldering applications involving mild stainless steel, copper, and non-ferrous alloys. Since it contains no chlorides, Superior No. 515 will not discolor brass due to de-zincification, and helps make post-solder metal finishing a quicker, cleaner process.Information provided by Superior Flux |
