## Description

Kester 951 Liquid Soldering Flux, No-Clean, 2-ounce Bottle - desertcart.com

Review: Works great, and better than syringe of paste - I had been using syringes of paste with gun squeeze handle. While Improving bench space wanted to try a cleaner flux that left less persistent messy residue to clean, and also wanted more convenient application in more compact package. This 'repackaged' liquid flux has displaced my tubes in only a few uses! Very clear, during and after soldering. Flux action works perfectly well. Super compact to stand on back of mat. My only caution is it is VERY liquid. May end up applying a smaller gauge blunt needle. I already had spares which had silicone needle covers, which I keep on this. That detail makes this flux and bottle a perfect permanent solution on my bench. Just ordered 2 more bottles. One for my mobile kit and one for spare. In spite of the price, it is less per ounce than the no-name brands, and presumably MUCH better quality and performs as desired. Definitely recommend for hobbyists that solder regularly and desire to level up after getting the cheap stuff during the learning curve.
Review: A mess free, trouble free, easy to use solution for hobbiest and professionals - I purchased this product at a glance and I have not regretted it. It goes on easy and cleans all soldering surfaces without making a mess. I normally go for paste, but this converted me to liquid. I don't work on electronics professionally, I'm just a humble hobbiest. As a hobbiest, I can tell you every brand of flux that works the best, that is easy to clean up etc. Kester 951 blows everything out of the water! I barely have to clean up after soldering a wire, sometimes I don't even have to. It's incredibly flammable, and that's the only con. The smell isn't so bad either, it smells pleasant when burned with an iron. I will buy this again when the time arises. The seller had it delivered a week earlier than expected, which was really awesome!

## Questions & Answers

**Q: where can we get msds and tds on this item - flux 951?**
A: You would need to contact the flux manufacturer on that.

**Q: Will it work with soldering aluminum?**
A: We do not think so. Aluminum requires any oxidation to be removed before processes such as welding. I do not know of any process for soldering aluminum. And this flux will not work.

**Q: What's the difference between this & 186  cleaner??**
A: Kester 951 is a liquid no-clean flux that is designed for soldering of conventional and surface mount circuit board assemblies. The extremely low solids content and activator system results in virtually no residue left on the assembly after soldering. 
Kester 186 is a rosin-based organic flux that is specifically designed for rework of conventional and surface mount circuit board assemblies. The low solids content and activator system results in LOW RESIDUE left on the assembly after soldering.

**Q: Does this item come with certificates of conformance from kester?  what is the expiration date on current stock?**
A: I dont recall getting a certificate of conformance, but I can tell you it works without incident on the small electronic sound wiring I use it on. The bottle has a DOM of 6/9/2021 and DOE of 6/9/22
