- Solder Iron or element surface oxidation，not easy adhesion of tin and the next welding, with rosin can quickly remove oxidation，making components more easily by welding, the effect is obvious.
- Fluxing excellent results,joint high intensity.
- Good insulation.
- No corrosion,IC and PCB for no corrosive.
- Smooth welding surface.No deterioration and no dry.Neutral PH 7土0.3.
