KappFree™ solder is a lead-free formulation designed specifically to replace lead solders in plumbing, electrical and electronic applications. KappFree™ is simple, effective and easy to use, in both manufacturing and field applications. KappFree™ provides superior joint strength, vibration resistance and thermal cycle fatigue resistance in both piping and electrical products. KappFree™ has been used successfully for over a decade in the lead-free manufacture of electrical and mechanical connectors, heat exchangers, and electronic components for harsh environments.

KappFree™ has been designed to accomplish three important lead-free objectives:

1. Produce a cost-effective lead-free composition to address environmental and health concerns,
2. Allow easy application at low temperatures with any heat source,
3. Provide superior strength and corrosion resistance to tin-lead solders.

KappFree™ also offers important advantages over silver brazing alloys:

• Lower material costs (up to 4 times more cost effective).
• Up to 4 times faster production due to ease of use and a lower process temperature.
• Faster post-production cleanup, often requiring only inspection.
• Non-Toxic – Lead-free and Cadmium-free
• Elimination of the effects of high heat used in brazing – base metal deformation, discoloration, segregation, annealment, and heat related oxide-scale formation, to name a few.
