No Clean Flux
Kester 985M is a low solids, halide-free, no-clean flux that is designed for wave solder, selective solder and touch up processes. 985M was developed for use with both traditional tin-lead and lead-free solder alloys. 985M exhibits improved soldering performance to minimize solder bridges (shorts) during all soldering operations. This flux is suitable for automotive, computer, telecommunications and other applications where reliability considerations are critical. As tested under J-STD-004A specifications 985M is classified Type ROLO.
