Water Soluble Flux


It has been devised specifically for use in the electronics industry. They are extremely active fluxes, which help rapid and efficient soldering of the most difficult to solder parts. The water-soluble flux is more active than the rosin based flux and hence defect free soldering is obtained even with PCB and component leads with poor solder-ability. There are three types of Water Soluble Liquid Fluxes used in wave soldering printed circuits having 10%, 20 % and 40% solid content.


Method of application foam type. Flux can be used for the WAVE / DIP soldering of all printed circuit boards to give fast production speeds and reliable soldering. Before using Water Soluble Flux, the components must be assessed as being able to with stand the necessary washing procedures.

It is important that the cleanliness of boards and components are thoroughly checked after soldering and cleaning. The usual procedure is to check the conductivity of the final rinse water as a measure of ionic contamination.

Flux Control

During Wave Soldering operation, flux thickens due to solvent evaporation. To restore it to the specific gravity add WS 71 thinner.

Removal Of Flux Residue

The residues, which must be removed, are quickly washed away by deionized water without the need of any added neutralizers or cleaners.

Technical Data

Safety Information

Take all normal precautions for its handling, use and storage. It should be used in a well-ventilated area. Keep away from sources of flame and heat. The prescribed containers must be stored tightly closed in a well-ventilated area.


It can be supplied in 5,10 and 20 Litres. Jerry can.
