K100LD: In response to demand for a low cost and low copper dissolution alloy, Kester has developed Ultrapure K100LD. Kester K100LD is a eutectic Tin/Copper alloy with controlled metallic dopants to control the grain structure within the solder joint, and to minimize the dissolution of copper into the solder pot. K100LD virtually eliminates the occurrence of common defects such as icicling and bridging. The improved grain structure also results in shinier solder joints than traditional lead-free alloy alternatives.

Kester 48 Activated Rosin Flux for cored solder wire was developed for lead-free applications to enable soldering of most common metals. Kester 48 has performance characteristics far exceeding standard RA fluxes. Kester 48 builds on the performance of its predecessor Kester 44 with instant-action wetting to provide fast and reliable solder joints.
