Soldering Flux

Products Details

The soldering flux is designed to help promote the soldering process. It is a chemical substance the protects the surface and prevents oxidation on the metal to be joined by soldering. The surface remains unchanged before and after the soldering process. The soldering flux is a natural soldering material with rosin as its primary component. With minimal smoke created, it does not pollute the working environment or negatively affect operator health.
