KappCu™ Tin-Copper NSF compliant solder replaces KappLead™ (Tin-Lead) solders in plumbing and Stainless Steel soldering applications. It is a low cost alternative to higher priced Silver solders and offers a wider workable range than KappAnt™ solders, allowing for joint build-up and adjustment during cooling.

This product complies with NSF/ANSI Standard 372: Drinking Water System Components – Lead Content. Product also Certified to NSF/ANSI 61, Annex G and conforms with Lead content requirements for “Lead-free” plumbing as defined by California, Vermont, Maryland, and Louisiana state laws and the U.S. Safe Drinking Water Act in effect as of January 4, 2014. Weighted average lead content < 0.25%; Solder and flux lead content < 0.20%. This alloy complies with the European RoHS and REACH directives. No lead, cadmium or mercury used in production.

Applications

  • Plumbing applications when joining Copper, Brass, or Stainless Steel
  • Situations where higher temperatures can be attained without harm to adjacent parts
  • Used extensively for large Stainless Steel products in the food service industry as well as potable water applications
  • Paired with Kapp CopperBond™ Flux
