Stannol Kolophonium Acid-Free Rosin Flux is an acid-free flux suitable for electronics. Colophony (also referred to as rosin) is an amber-coloured brittle, glassy solid at room temperature and becomes liquid at temperatures of 80 to 100°C. In practical use, small amounts can be chipped off and dissolved in isopropyl alcohol (IPA), or it can be melted by gentle heat from a soldering iron. The resulting liquid can then be brushed or dripped onto the item to be soldered. * Supplied in 20g packs https://elecena.pl/product/27181168/stannol-174081-rosin-20g 2024-11-08 https://elecena.pl/product/27181168/stannol-174081-rosin-20g 2026-07-02
