Kester 24-6040-0039 is a Fully Activated Rosin Cored Soldering Wire. 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.
