Provides some flux like action for soldering.
It's super cheap!
Comes Securely packaged.
Easy clean up with the right solvents. Leaves a lot of residue.
Flux action is on the weak side.
Can be a heck of a mess when chipping a piece out of the block. I needed to get more flux for soldering and figured i'd give this a try. Works well for the price, be ... Read more
-Like most people say it is the best thing u can get for making your own solder flux. -Its easy to get it ready for soldering but needs some personal fine tuning to your own liking and use. -It is sticky as hell and even worse once u got the alcohol mixed up with it but there is nothing DX can do about this it is just the product and it is supposed ...

- A simple and useful product
- 2 20g boxes of Rosin
- Seems refined well enough for my needs I wouldn't mind if it came in a better container or bigger blocks. I would like to see a 80g option available for purchase. I have found that for best results you want to mix in a ration of 40-70% rosin with 30-60% alcohol but add 2-4% glycerin to the mix. ... Read more
Clear hard rosin for making homebrew flux for soldering. No corrosive residue has been left on stuff I have used it for. I crushed it and dissolved it in isopropyl alchol.
All of it dissolved so no random solids in it either! None that I have found yet.
I have no way of verifying the claim of low KOH content, but it appears to be fairly low because ... Read more
This stuff is very inexpensive yet effective! What I did was crush it into a powder, the particles being about the same size as granulated sugar or table salt, dissolved that into 100ml of ~99% isopropyl alcohol (I used the 'salting out' method of removing the water) along with about 1.5ml of Glycerin. At first it didn't look or work like my commercial ... Read more
I use it as soldering flux solved in isopropyl alcohol.
It can also be used to protect PCB from oxidation. For this I just dissolved as much colophonium in the alcohol as possible. After covering the PCB with this, it dries within 1 - 2 days to a glass-like, solderable cover. It's not too easy to get it out of the paper box. But that's the only con.... Read more
This is great stuff, I use it a LOT when soldering my electronics projects at home. Just mix it up according to the patent supplied in another review and your on your way to better soldering jobs and better circuit performance. Might not end up being the worlds most powerful flux after mixing but then again that is the reason behind using non activated ... Read more
I used this to make my own flux. I followed the directions that I found her on the reviews. I crushed up one box, put in a container added about 60% of the volume of rubbing alcohol a little bit of vegetable glycerin and a day later I had the best and cheapest flux I have ever owned. You have to wait to be able to use this as flux. If you are like me ... Read more
Dissolve it in Isopropyl or Ethanol, heat it, let it cool and the alcohol evaporate a bit. You get viscous colophony flux that won't flow away until you solder. With more alcohol, you get a liquid for brushing onto a PCB or sticking wires in. It's a bit hard to dissolve a block, you have to break up the large block into smaller pieces.
The block is ... Read more
This is just awesome. You can create a very efficient, very cheap solder flux with this item. Simply add some IPA (isopropylic alcohol) and some drops of glycerin, wait 24 or 48 hours and voilà. You need time for the rosin to melt in the IPA, if you need sodler flux RIGHT NOW ... it "could" be a con. Finding IPA could be a bit hard depending on your ... Read more
