We have two type fluxs. Rosin flux and water-soluble fluxs. Its rosin from super pure rosins suitable for use in electronic applications. All products are high efficiency, non-corrosive non-conductive and reliable. Our rosin fluxs are always highly effective in their intended applications. Water soluble fluxs are considered highly emcient because of the extremely minute amount of residue left after soldering And can be thinned with of HCFC or AK-225 to increase flow and decrease residues.
