As per title, Does anybody know what the name of this paint is, Usually seen on clothing shop racks and sometimes gardening tools, It's a hammered,dimpled finish that when dry is black and silver in mottled pattern,just like Hammerite.

I do believe it's Stove Enamel, very very hard coating. Looks like this

I think stove enameling is a process not a colour.I had a load of scooter parts stove enameled years ago and it was very similar to powdercoating.
This was the first result when I googled hammered powdercoat.

Yes it is a process, i didn't say it wasn't. But the finish the OP is on about is a stove enameled hammered finish (as per picture).

And stove enamel is not like powder coating, you can cook stove enameled parts after the process, and it won't come off. Powder coating is basically melted plastic, so if re-heated it'd melt!!

So I guess stove enameling a better process than powder coating (more durable?).
Do many places do stove enameling anymore or has powdercoating taken over?

 

[danelectro]

Yeah Keith, very much more durable, I had some bits done a few years back, they're still as good as the day they were done!!! you even have trouble scratching it, it really is hard.

I'm not sure of the exact process, but it involves very high temps.

As to whether powdercoating has taken over, well it'll never beat stove enameled stuff, but I guess it depends on the application. If you can get away with powder, then all well and good, but you'd never be disappointed with SE

Thank chaps for your the fast replies. the radiator looks the same as the examples I have seen, Isn't stove enameling virtually fusing a glass hard material onto the base metal.the black/silver finish must be using the two different colours that are non miscible at stoving temperatures.

Depends on the powder, the most common is probably polyester, it cross links and can't be remelted, similar thing for epoxy powder.
Just read the link and they mention hammer and stoving, so it's probably stoved, but my local powder coater does hammer tone and he stopped stoving in the 80's.
Not completely off topic, the clear on Harley paint work is powder coating.

Stove enameling is wet enamel sprayed/dipped and then cured at elevated
temp[stoved].
The glassy finish is vitreous enamel. Just like the kits to make badges you saw when you were a kid, you heated a bit of metal and painted glass powder on and it fused together, into a mess usually;-) Think enamel badge..

Stove enamelling
Stove enamelling is like air-drying paint, but the curing is accelerated by stoving at 120 degrees Celsius. It is sprayed with the sort of spray guns you would expect to see spraying a car in a garage.
