Kester 282 Rosin Mildly Activated Sn63 Pb37 Soldering Wire, 66 Core (3.3%), 0.020 Inch Dia, 1 lb Spool, 24-6337-7400 (2463377400), MFR ID 24-6337-7400 (2463377400)

The Kester 282 mildly activated rosin flux core consists of high quality grade WW rosin to which a very small amount of an extremely effective activating agent has been incorporated. 282 is classified as type ROL1 flux under IPC ANSI/J-STD-004 Joint Industry Standard. It was formerly classified as type RMA per MIL-F-14256. Rosin core 282 has particular application where difficult assemblies are to be soldered but the flux residue must be electrically inert. - 282 Rosin-Cored solder has been developed for use in the electronics industry where a more active flux than plain rosin is required but where highly activated fluxes are considered potentially conductive.
