Soldering Fluxes

Soft Solder Flux 1S is a highly active liquid flux recommended for use on stainless and carbon steels, and is active up to 350°C where it possesses good wetting and spreading properties. The flux may also be used on non-ferrous alloys where there is a need for an active flux.

Soft Solder Flux No. 2S™ is a flux with reasonable wetting properties up to 300°C. It is particularly effective with the tin based soft solders such as P5™ and LMl0A™.Soft Solder Flux No. 2S™ is a liquid intermediate / semi-corrosive flux for use on copper and brass.

Soft Solder Flux No.3S™ is a paste flux active up to at least 350°C.It is widely used on carbon and stainless steel with solders such as P5™ and LMl0A™ and is effective on copper and brass with all solders including LM5™ and A5™.
