5RMA-RC and 5RA-RC are heat-stabilized rosin fluxes designed for soldering with preforms or wire. They are formulated for use with a wide range of temperatures and metallizations. Both fluxes are free of materials listed in the REACH SVHC list (Q2, 2015). 5RMA-RC is a no-clean, mildly activated flux. 5RA-RC is compatible with Pb-free alloys, as well as with high-Pb and SnPb alloys.
