Electrostatic Magic air pressure??
Morning all
Could anyone confirm to me what the ideal air pressure is for using the Electrostatic Magic powder coating kit??
The instructions state the ideal as being "1kg" which seems to me to be a strange unit for measuring pressure.
Cheers

They probably mean 1kgf / sq cm which is 1 bar or about 14 psi.

I have one I haven't tried yet, but it says 10-30 psi.
The instructions said to get everything hooked up properly, powder in, compressor on, and then set the pressure to 10 - 30 psi.
I can't do anything until spring - that takes a while around here. I was going to use a heat gun (SWMBO wouldn't let me get another oven,
saying it would take too much room in the garage). It did say that it shouldn't cool too fast or it gets orange-peely, so I have to wait. I was
going to use the garage.

Thanks guys - i have been using 30psi but was wondering if it was actually too low!!
Yes I am doing this in my garage. I bought an Infra Red patio heater off ebay for under £30 delivered and with a 2kW output it seems well up to the
job. I heat gun would be useful to do smaller parts and get into the corners mind.

I was lead to believe only living things could feel Infra-Red heat. My Vivarium has an infrared heat mat - which does nothing to warm the ambient
surroundings but warms the snakes I keep. I have to use a lamp to provide ambient heat...
Will Infrared light do anything for powder coating? Unless it is something to do with pigment or plastic used....

errrr well yeah - it will cure it!! 
It has been melting the powder coat within a couple of minutes so has done a pretty good job. Curing one end of the roll bar, the heat generated was
enough to make the other end almost untouchable so its certainly heating up the bar well.

Infra-red will heat anything which will absorb the particular frequency of radiation of which IR is comprised.
In a nutshell anything dense enough to slow the wave significantly.
Doesnt have to living, works on machines in workshops very well - e.g. Schwank heaters high up on workshop walls etc

I can say that using a heat gun in temps of -5 c, only works "sort of". When I left the gun on a small piece of alu for 15 mins it turned
out OK, but bigger pieces were a bit bumpy. I need a patio heater or similar, which gives more heat, and maybe wait til it's a bit warmer
out.
On another note, the powder stayed very contained. Not a difficult clean up, other than tangled wires! In all, I proved the system works; just needs a
bit of ironing out, as it were.

If you do that doesn't it stick to the iron?
