835 is a rosin-based liquid flux with moderate activity. It is composed of pure Water White (WW) grade gum rosin in a unique solvent system combined with highly effective activators. Post-soldering residues are non-conductive, noncorrosive, hydroscopic, non-tacky, and fungus resistant.

835 can be used for 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.
