Smooth, superior quality petrolatum based flux, especially formulated for use in extreme climate temperatures all year long. Unlike some paste fluxes which become semi liquid when stored at high temperatures and stiff at low temperatures, Solderlene will not lose its consistency. For use with all soft solders including new, higher melting alloys. For sweat soldering most common metals except aluminum. Chemically removes oxides on contact and prevents oxidation during heating.
