Kothari Metsol supplies premium rosin core solder wire and solder wire with flux in bulk quantities across India, ensuring consistent performance and reliable delivery.
Yes. If the solder wire uses no-clean or mildly activated (RMA) rosin flux, post-soldering cleaning is usually only needed for aesthetics, not functionality.
Flux removes surface oxides and acts as an oxygen barrier during soldering, enhancing solder flow and bonding quality.
Rosin core solder is preferred for electronics—acid flux is too corrosive and may damage components and patterns over time.
Rosin core soldering wire is solder with a rosin-based flux core that melts during soldering, preparing the surface and enabling precise, high-quality electronic connections.
Kothari Metsol provides lead-free rosin core solder wire designed for eco-friendly soldering with excellent flow and strong bonding.
We use Water White (WW) Grade Rosin flux, which is non-corrosive, mildly activated, and ideal for clean, reliable solder joints. It provides excellent wetting and leaves minimal residue after soldering.
