Rosin Soldering Flux Paste, 30 g, 50 g or 100 g

Help solder flow onto suitable electronic joints with rosin flux paste. The paste format lets you place flux where it is needed during compatible PCB work and small wiring repairs.

✅ Prepare the joint for soldering - Flux helps remove surface oxides during the heating process.

✅ Apply a controlled amount - The paste consistency is convenient for a small target area.

✅ Choose a practical tin size - 30 g, 50 g and 100 g options suit different workshop needs.

Use a Little Flux Where the Joint Needs It

Apply an appropriate amount to the prepared joint and solder using the correct temperature and technique. Flux supports wetting but does not replace clean surfaces and a sound mechanical connection.

The rosin-based paste is sold as a no-clean formulation. Follow the circuit and flux instructions for any residue cleaning, and use effective ventilation during soldering. Solder wire and tools are separate.
