- High Activity Rosin Formulation
- Two Highly Popular Alloys
- Solderability on Nickel and Other Difficult Metallizations
- Good for Metals with Excessive Oxides
- Classified as ROM1 per J-STD-004
Kester 88 activated rosin flux for cored solder consists of high quality Grade WW rosin to which has been added an extremely effective activating agent. This rosin flux formulation is similar to the popular Kester 44 which has been the standard of the electronics industry for decades. The degree of activity has been increased, however, to be able to provide better fluxing action in those cases where Kester 44 flux will not wet metal surfaces which are excessively oxidized. Kester 88 flux core is classified as ROM1 per J-STD-004.
Kester 88 activated rosin flux is used for applications where organic flux residue is too corrosive and conductive and a more active flux than normal activated rosin flux is required. Kester88 flux is recommended for difficult-to-solder metals such as nickel or for metals with excessive oxides.
