The RSF-R80-2 is Rosin SOldering Flux from CAIG. The RSF Rosin Flux is a mildly-activated rosin flux that is considerably more active than water-white rosin. Although its activity closely approaches that of fully activated rosins, it still conforms to all of the requirements of Type RMA (Rosin Core, Mildly Activated) of Federal Specication QQ-S-571. The RSF paste flux meets DOD-STD-2000 & also the IPC-J-004 standard for type ROL0, the lowest residue corrosivity category.

The active ingredients in RSF-R80 are non-ionic and non-conductive even in the presence of moisture. Like rosin, it becomes active only at elevated temperatures, reverting to an inactive state at room temperature. It is recommended for all applications where post-soldering cleaning is not feasible, and the residue must be highly insulating.
