Kester ""44"" resin core solder is designed for electrical, electronic and aerospace applications. 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. An outstanding performance feature of this flux is the “instant-action” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering.
