835 is a rosin-based liquid flux with moderate activity. This rosin flux is composed of pure Water White (WW) grade gum rosin in a unique solvent system, combined with highly effective activators. Post-soldering residues from this RA liquid flux are non-conductive, non-corrosive, hydroscopic, non-tacky, and fungus resistant.This rosin soldering flux can be used in both automated and manual soldering applications. It is great for general purpose soldering of PCBs, wire, cable, and semiconductors. It is also ideal for solder coating or tinning leads. It may be applied by spray or foam, or by wave fluxing for wave soldering applications.We also offer no-clean halogen-free flux, lead-free no-clean flux, and lead-free water-soluble flux in liquid format.For a paste flux, try MG’s 8341 and 8342.
