Water-soluble gel-like liquid flux FVL-20G is a new generation universal organic eco-flux that does not contain volatile solvents.
Developed as a versatile, non-toxic and non-corrosive to metals, water-washable liquid soldering flux for non-ferrous metals as a replacement for alcohol-based liquid fluxes.
FVL-20G consists exclusively of substances used in the food and cosmetic industry, which determines its safety for health.
Designed for soldering printed circuit boards, as well as for soldering copper, nickel-plated surfaces, brass, galvanized surfaces, copper alloys, some types of steel.
A distinctive feature of the flux is that it tins oxidized and darkened copper very well, without causing further corrosion.
This property allows copper, brass and other copper alloys to be soldered without first stripping the darkened layer.
The special water-soluble composition of the flux provides easy rinsing with water and polar organic solvents (ethyl alcohol, isopropanol, acetone). The gel-like liquid consistency makes it easy to apply the flux to the PCB without the use of volatile solvents, which is very important in terms of fire safety.
The main difference from classical fluxes is the absence of inorganic acids and their salts (chlorides and hydrochlorides), amines and amino alcohols (ethanolamine hydrochloric acid, diethylamine hydrochloric acid), ammonium salts in the composition of FVL-20L. Since the flux does not contain compounds strongly dissociating in water, it does not corrode metals.
The flux does not contain toxic compounds and its vapors are not hazardous to health, unlike many other active fluxes containing halogens and toxic organics.
The ability to dissolve metal oxide layers is due to the ionization of active components only at high temperatures; under normal conditions, the flux has no noticeable activity.
When the flux burns out, a yellow slag forms on the tip of the soldering iron, which can be easily washed off with water.
It should be understood that any water-soluble substances in the presence of moisture have electrical conductivity determined by the degree of dissociation, therefore it is very important after the end of the soldering of electronic devices to completely wash off the flux residues with deionized or distilled water.
