Ingredients paraffin oils, rosins

Review: Awesome stuff for electronics! - I bought this after reading some other reviews that suggested this was great for electrical work. I've been away from hobby electronics for many years and i'm only just returning to it, so needed to stock up with some decent soldering accessories. Having read about rosin flux, I was expecting a vile, nasty product which creates a lot of fumes during use and stinks the house out. Really not the case with this product. Obviously you should never breathe solder/flux fumes anyway, but I really didn't notice any odours emanating from the flux, which makes it a pleasure to use. The consistency is as it should be, and I find it is easily applied to joints using small wooden coffee stirrers (they make great applicators!) Although i've only used it for soldering wire connections so far, my solder joints have been massively improved by this stuff. The solder flows easily and very quickly (I use 60/40 Tin/Lead solder) and leaves connections strong and shiny. I was a little surprised to find the tub only half full when opening it, but it is indeed 50g in weight. Not sure why they did this, but I guess there must be a reason why they didn't just fill the tub. That said, there is still plenty of product in the tub. For what i use it for, i'm not expecting to have to reorder any again any time soon. Highly recommended!
Review: Best flux going - Brill flux - second tub for me . Really helps solder flow and you only need a smidgeon…

### ⭐⭐⭐⭐⭐ Does the job and does it very well
*by K***N on 20 May 2020*

OK Im not an expert in the field of soldering but I like to dabble as a hobby with electronics. I got this mainly to solder a repair on the washing machine, a snapped thickish stranded wire. First attempts before I got it were rubbish but this flux chaged the game and I produced some decent joints in no time. Its worth having a pot, im very happy with mine
