SRA Solder 135 Rosin Paste Soldering Flux for Electronics - Lead and Lead-Free Boards, Copper Wire, No Clean Residues (2oz Jar, 30ml Dropper)

The SRA 135 rosin-based flux is a superior choice for electronic repairs, as it contains no zinc chloride or ammonium chloride, which can be harmful. Once the job is finished, the rosin leaves a protective coating over the soldered area, ensuring long-lasting results.

Our USA-quality flux allows you to achieve the soldering results you desire. The rosin paste flux is impurity-free and offers superior solder flux paste wetting performance, resulting in perfected rosin flux soldering.

Unlike the paste flux wax found at hardware stores, the SRA 135 acid-free electronics soldering flux is the safe and effective choice for electrical and electronic applications. The semi-solid solder wax consistency of our flux provides you with superior control over the application, making it easy to dip copper electric wires or apply the electronic rosin flux to PCBs and watch the solder flow.

The SRA 135 flux is a type RA (Rosin Activated) Flux with an Active Temp. Range of 93 – 315°C / 200 – 600°F, making it suitable for a wide range of applications. This listing is for one 2oz (56.6g) jar of electrical flux paste.

You can use this flux for soldering DIY electronics projects, including Car Audio, Stereo & Hifi, Computers, RC Vehicles, Drones / FPV, Musical Instruments, Gaming Consoles, Model Railroad, Arduino / Raspberry Pi, and more. The impurity-free and superior solder flux paste wetting performance of the SRA 135 rosin-based flux ensures reliable and long-lasting results for your electronic projects.

In summary, the SRA 135 rosin-based flux is the ideal choice for electronic repairs and DIY projects. Its zinc chloride and ammonium chloride-free formulation, protective coating, and superior soldering performance make it the preferred flux for a wide range of electrical and electronic applications.
