Kester Type R Rosin Based Fluxes

Kester rosin fluxes are formulated with high quality purified rosin conforming to LLL-R-626 in specially blended solvent systems. The choice of the proper flux formula is based on the soldering application, desired rosin percentage, type of solvent and the activity level required.
