Felder Soft Solder and Tinning Paste, 21616070, 1 Kg

Ready-made soft solder metal paste for soldering, tinning and pre-tinning. Based on zinc chloride and ammonium chloride in organic formulation with metal powder. Apply paste thinly with a brush on the part which has to be tinned and heat up equally. Afterwards remove the flux residues with a moist cloth. Subsequently you may increase the layer thickness with rods or wire solder. The flux residues are corrosive and have to be thoroughly removed with water (if requested maybe neutralisation, ultrasound).
