Kester Lead-Free Wire Solder

EWD Solutions offers several types of Lead-Free Wire Solder from Kester.

Lead-Free No-Clean 275 Wire Solder: Kester® 275 No-Clean Flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 275 No-Clean Flux results in an extremely clear post-soldering residue without cleaning. The unique chemistry in Kester 275 was also designed to reduce spattering common to most core fluxes. Kester 275 can be used for both lead bearing and lead-free soldering.

Lead-Free Activated Rosin 48 Wire Solder: Kester Activated Rosin flux is a very high activity rosin flux used for difficult to solder metals. It was developed for lead-free applications to enable soldering of most common metals and has performance characteristics far exceeding standard RA fluxes. It builds on the performance of its 44 Rosin Flux predecessor with instant-action wetting to provide fast and reliable solder joints.

Lead-Free Water Soluble 331 Wire Solder: Kester® 331 Organic Flux is a water soluble formula for use in flux-cored wire. This cored solder version of the popular 2331-ZX Neutral Organic Water Soluble Liquid Flux is more effective than rosin fluxes in soldering difficult metals. The same fast action and mild properties are exhibited with 331 Organic Flux as with the liquid 2331-ZX. This flux is more heat stable than most organic fluxes, resulting in minimal smoke and odor. The residue can be completely removed with a simple water rinse.

Many other Kester products are available at EWD Solutions including bar solder, solder paste and solder flux.
