Kester 44 Rosin Flux is a turned on rosin formula for use in flux-cored solder wire. Kester 44 Rosin Flux has actually virtually controlled the field of triggered rosin core solders for more than four years. An impressive efficiency attribute of this change is the "instant-action" moistening habits. The high flexibility as well as fast-spreading activity of this change results in more trusted production line soldering.
Industry standard for decades
