Kester 24-7068-6403
Kester “331” Lead-Free Organic Water-Soluble Flux is more effective than rosin flux when working with difficult-to-solder metals. Organic flux is more heat stable than most organic fluxes and the residue can be completely removed with a simple water rinse. Neutralizers, saponifiers or detergents are not necessary for residue removal.
