TSF-WS917-1 is a water-soluble viscous flux. Post-reflow residues are completely soluble in water and can be rinsed off at temperatures as low as 40 ° C without the need to add cleaning additives.

Kester TSF ULR-18 is a no-clean ultra-low residual tack flux. To meet this market demand, Kester has developed an ultra-low resolution viscous flux with a reflow residue weight of less than 10%, which is reduced by 3 times compared with traditional rosin-based viscous flux, and the trace amount of residue is very reliable , Compatible with post-processing materials.
