How long will the powder hold until it needs to be cured?

[trsick]

Hey All:
I just finished my big oven (8'x8'x8') last week. I plan to powder many items & then bake them all off at the same time at the end of the day. My question is... How long will the powder stay static while I wait to cure? Will I risk loosing the static charge if I wait too long?
Thanks
Bob

It should be okay. Just stack the pieces in the oven where they won't be contanimated until it is full.

i agree the biggest problem with doing that is contamination of dust particles floating around

you won't have any problems
I've done up to 15 parts at the same time
just don't mix up colors in the same batch,learn that the hard way

In regard to storing the pieces in your oven, would it be OK to bring the oven up to temperature with the pieces hanging on the rack?

Actually I believe the concensus is that bringing parts to temp with the oven Helps the process, under the chrome thread, its recommended as a process to try in order to get your chrome to cure best.

I always pre heat or out gas the part at 450f then turn the temp to 200f and wait for the oven to cycle on at that temp so i know it is at 200f. then i spray it close the door set to the temp i need for full cure and set the timer. I never shoot cold parts and hot parts coat just like there staticly charged. give it a try if you have not been coating this way i think you'll be suprised at how much easir and better quaility work you will turn out.

I tried it today and didn't see any problems with it.

I have a small oven and do small parts I machine. I found it helpful because I could load the oven without hurrying and getting burned, messing up the powder and having to re-shoot the parts. And by adding the pieces in the oven while its cold, allows me get more pieces in the oven per run, about twice as many as I was doing before.

you lost me there, you do load and spray or you powder cold then put them in the oven
