Kester high activity, rosin activated flux-cored solder is excellent for instant wetting action. Excellent solderability to a wide variety of metalizations.
Kester KW4455 high activity, rosin activated cored wire is excellent for instant wetting action. Although "44" is an RA-based material, the residues are non-corrosive if left uncleaned. 0.031‚ wire diameter. 1 lb spool.
An outstanding performance feature of this flux is the instantaction‚wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering.
