KappFree™ Tin-Copper-Silver solder is a Lead-free, Cadmium-free formulation designed specifically to replace KappLead™ (Tin-Lead) solders in standard Stainless Steel, Copper, and Brass plumbing applications. This solder is simple, effective, and easy to use in both the installation and repair of Stainless Steel, Copper, and Brass. KappFree™ provides less joint strength, vibration resistance, and thermal cycle fatigue resistance than KappZapp™ solders, so it is used less often in high pressure or very cyclical heat exchangers, or HVAC systems.
This product complies with NSF/ANSI Standard 372: Drinking Water System Components – Lead Content. Product also complies with 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.
Benefits & Features
KappFree™ has been designed to accomplish three important Lead/Cadmium-free objectives:
- Produce a cost-effective Lead/Cadmium-free composition to address environmental and health concerns – meet ASTM and NSF Food Grade and Potable Water Standards
- Provide superior strength and corrosion resistance to KappLead™ (Tin-Lead) solders
- Allow easy application at low temperatures with any heat source
Applications
- Installation and repair of Stainless Steel, Copper, and Brass plumbing
- Electrical and mechanical connectors
- Heat exchangers
- Electronic components for harsh environments
- Paired with Kapp Comet™ Flux
Benefits over Silver Brazing Alloys
- Lower material costs (up to 4X more cost effective)
- Up to 4X faster production due to ease of use and lower process temperatures
- Faster post-production cleanup, often requiring only inspection
- Non-Toxic – Lead/Cadmium-free
- Elimination of the effects of high heat used in brazing – avoiding base metal deformation, discoloration, segregation, annealment, and heat related oxide-scale formation, to name a few.
