Thermaltronics TMT-FP-1 Rosin Flux Paste, 2.0 oz (57 g)

The packaging now includes a foil seal, like you would find on a pill bottle.Flux works great, nice consistency, easy to use, no complaints. Would buy again.

A very good product, easy to use, delicate and resistant to temperature differences, does not allow harmful UV radiation to pass through despite being transparent. Pleasant to the touch. You could say it's an aphrodisiac.

Great product, performs as expected. The only thing I don't like is the can its packaged in. It's difficult to pry open. To make the task of removing the top easier, I used a flathead screwdriver to make a indentation in the bottom section of the can. I did this by: nserting my flathead screwdriver in between the top and the bottom sections of the can, held the can steady, and then I lifted up on the handle while applying downward pressure on the lip of the bottom can with head of the screwdriver. The bottom lip should have a "V" shaped indentation that will allow easy access to the flux.

Works great on copper and brass to solder parts together or to tin wires.

First time using flux but it makes all the difference. I quickly learned that a brush will apply WAY too much for what you really need. I used an awl or other pointed tool to get a tiny drop of material to apply, preheated, and solder would flow like gold. It’s a bit gloopy but have no experience for comparison. This will likely be enough for a lifetime at the rate I work.
