Feature：

1. This solder Flux presenting a flawless welding solution rooted in rosin. It is acid-free, lead-free, and spill-resistant. The high purity of the rosin solder Flux establishes it as an outstanding companion for repair and welding tasks.

2. Non-Corrosive: Rosin is not conductive in dry conditions and has good insulation. Is not corrosive to metal substances such as circuit boards.

3. Oxidation Resistance: Anti-oxidation effect on soldering iron head of gold-copper alloy substrate. Solder flux for semi-solid, not easy to dump.

4. Strong Applicability: Flux is suitable for welding instruments, gold, copper, tin, iron and other metals. Ideal for electronic welding, repair and rework.

5. Improves solder flow for accurate and controlled soldering, Facilitates the soldering process.
