I would appreciate your advise.** A: I have not used it for such and in the past when soldering copper foil around glass I have always found it best to use pre-fluxed solder because it enables one to limit the soldered area. LO CO is a messy flux to manage **Q: is it an acid flux** A: The product does not seem to be acid base material. I tell what it works very indeed and have no complaints **Q: Is this okay to soldering mobile and other devices?** A: I think you'd struggle to apply it on microchips/ electronic circuits. This is aimed at plumbing pipework. For PCB and electronic work I would advise looking for a flux 'pen' applicator...this is FAR too thick for what you're looking for. **Q: Is this flux suitable for brazing** A: No, it is the wrong kind, check out " how to brew by John Palmer" for chapter and verse. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by S***Y on 4 June 2026* Excellent highly recommend. ### ⭐⭐⭐⭐⭐ Ok *by R***B on 13 May 2026* Works well ### ⭐⭐⭐⭐ Excellent Soldering Paste - Applicator? *by M***M on 2 September 2020* First off the actual paste is probably the best soldering paste I've used for general purpose soldering. It seems to very quickly wick into any joint faster than most and really helps draw in the solder. What I didn't like was the brush applicator which, when pulled out of the tub is just a big gloopy mass because of course it's jammed right into the paste. This means small applications are impossible near enough. To be honest I'd rather there was no brush at all. However, because of the quality of the paste this is a five star product dropping a star for the awkward brush applicator. ## Frequently Bought Together - LA-CO FLUX 125GRM BRUSH IN CAP - Rothenberger 67022 Plumbers Soldering Mat up to 1000 Degrees C - Neilsen CT2803 Wire Brush Pipe Cleaner - Heavy-Duty Steel Bristles for 1/2" and 3/4" Internal and External Pipes --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/47876993-la-co-flux-125grm-brush-in-cap](https://www.desertcart.be/products/47876993-la-co-flux-125grm-brush-in-cap) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-25*
