All Zinc-Free soldering fluxes are RoHS compliant.
Superior SuperSafe® No. 30 soldering flux is an excellent general purpose flux that contains no Zinc Chloride and is a non-hazardous product. Learn more about the entire family of Superior No. 30 SuperSafe Soldering Flux.
Superior No. 68 soldering flux contains no Zinc Chloride or Ammonium Chloride. This ZC-Free® flux is a versatile organic acid flux that is both VOC-Free and non-hazardous.
Superior No. 465 soldering flux is a Zinc-Free, Ammonia-Free, metal halide flux. It is one of the strongest tinning fluxes on the market and can solder stainless steel, as well as certain difficult-to-solder metals that can not soldered with even a Zinc Chloride-based flux.
Superior No. 515 is an Inorganic Acid flux that provides a self-neutralizing activator that can be used for a variety of industrial applications where zinc-chloride fluxes are not wanted for safety or over-activity reasons.
Superior No. 520B radiator flux is a zinc-free, bromide-based amine salt flux specifically designed for copper-brass radiator assembly soldering. The high concentration of No. 520B allows for a great amount of dilution, resulting in huge savings for production operations. This radiator flux can also been used for soldering brass header dips to the end of the radiator core with immersion or some other method of soldering the brass tubes to the brass header.
