Can't see the bit about lack of zinc chloride. What is it made from? Is this a less poisonous flux? Why do YOU like it so much? You've got my interest...

It has a nice tin: I like the flux brush holder!

If you fancy a swap of a sample of Fluxite for a sample of the German one by post, PM me.

Just saying to expect the flux to burn if you overdo the heat.
But I find Fluxite will not burn if you solder properly.
That German flux paste I must read about if I can find details in English

It's known as 'solder paint' in this country, Fryolux is the main brand. A paste of zinc chloride and solder powder. There is a lead free version. It's more common in engineering workshops that in use by plumbers. Probably because it's rather expensive and zinc chloride is pretty corrosive so fumes and spitting are an issue.

Hang on. Matchless tells us it doesn't have zinc chloride, Chuck says it does.

Fluxite and Yorkshire contain 10-15% zinc chloride, Everflux over 4%, LaCo doesn't seem to have any.

Actually, what I meant to say is 'solder paste', which is a mix of powdered solder and flux, is usually known as 'solder paint' in the UK and I also gave an example of the brand I'm most familiar with, which does contain zinc chloride. I don't what type of flux is in Matchless's stuff, I've never seen his brand in this country.

It does not have any zinc chloride, it's free of zinc chloride.

Here mate give it a go,

You won't regret it. I think it's a real good stuff when soldering a lot.

Oh, I see. You flux up with it and then heat and the solder is already in the flux.

Like the reverse of resin-core solder as used in electronics.
