MG Chemicals 8342 RA Rosin Flux Paste, Amber, 50 g Jar (8342-50G)

Great product

Packaged well and works as advertised. Glad to have it in my soldering arsenal.

Definitely does what I needed, it performs great 👍 clean up afterwards with the highest content of ipa % you can get and Bob's your uncle! The smell reminds me of the rosin that used to come in the Deoxit jars.

The flux works really, REALLY well - as expected of MG Chemicals, but the way the syringe is put together is kind of annoying, since the plunger part keeps falling out.

this is a must have product if your doing soldering. the rosin flux in solder line is not enough for most things even properly cleaned solder pads will benefit greatly from some more flux. this may not look like a lot but I have made hundreds of connections and still have most of it left. pro tip wear gloves this stuff is messy,sticky and does wash off your hands very easily with hand soap. though dish soap takes it off pretty easily. use this stuff outside and with a fan blowing over your work as flux is toxic and builds up in your system. having a headache for days was not fun.

I love this stuff for desoldering through hole components. The synthetic and no clean fluxes on the market just aren’t penetrative enough when mixing unleaded with leaded for through hole desoldering work. This is the only stuff I trust that won’t have me overheating the PCB. Synthetic stuff is great for surface mount but you just can’t beat real Rosin flux for through hole! It does have the downside of having to clean it much more thoroughly but it’s worth it to not be battling different heat settings for different types of solder.

I have used this product for a couple years and have zero issues with the way it works, so I just ordered another bottle. I was shocked when I opened it to find that the bottle is less than half full. I guess you pay by weight (50g), but for $13, why not just fill it, or use a smaller bottle so that the flux is easier to get to (the walls of the bottle could be 30% to 40% shorter).

Once I opened the container, the smell told me all I need to know. Perfect quality! I was going to give up on my soldering Iron tip as I couldn't clean the oxidized at all. Tried different method, unsuccessful. This paste cleand it in a matter of seconds. Although it's not good for soldering tips, but sometimes I have to use it. Just keep in mind to keep your soldering iron tip covered with tin to prevent it from corrosion.
