Solder 135 Rosin Paste Soldering Flux for Electronics - Lead and Lead-Free Safe Clean Residues (2oz Jar)

The SRA 135 rosin paste flux is an impurity-free, high-performing solder flux paste that delivers superior solder wetting results. This petroleum/rosin-based flux contains no zinc chloride or ammonium chloride, making it a safer choice for electronic repairs compared to other flux options.

Once the soldering task is complete, the rosin flux leaves a protective coating over the soldered area, ensuring the integrity of the connection. This USA-quality flux allows users to achieve the soldering results they desire, thanks to its exceptional solder flux paste wetting performance.

Unlike the paste flux wax found in hardware stores, the SRA 135 acid-free electronics soldering flux is the safe and effective choice for electrical and electronic applications. Its semi-solid solder wax consistency provides users with superior control over the application process, allowing them to simply dip copper electric wires or apply the flux to PCBs and watch the solder flow seamlessly.

The SRA 135 flux is a type RA (Rosin Activated) flux with an active temperature range of 93–315°C / 200–600°F, making it suitable for a wide variety of soldering projects. This listing includes one 2oz (56.6g) jar of the electrical flux paste, which can be used for DIY electronics projects such as car audio, stereo and hi-fi systems, computers, RC vehicles, drones/FPV, musical instruments, gaming consoles, model railroads, Arduino/Raspberry Pi, and more.
