Pretreatment

[OKTRX450R]

OK, so I am going to powder some pieces on my atv...
1: I bead blast the pieces,
2: wipe them down with paint thinner or final clean,
3: preheat to 200*,
4: shoot powder,
5:bake at 375-400* until yummy.

Is this correct?

Should I use the Iron Phosphate? Pros/cons...

Thanks for the help!

Re: Pretreatment

Sounds correct to me...But when pre-heating (outgassing) I usually keep it around 250-300 and I outgass it for 10-15 minutes.

Re: Pretreatment

Normally you don't need to pre-heat parts unless you need to off gas them.
Old cast iron or cast aluminum..
I was always told to off gas at a higher temperature (50-75+) than you're going to cure the powder at.

Re: Pretreatment

thats what I've found work best- out-gassing at a higher temp, I do about 450 to 475 degrees- I've heard either hotter or longer than your curring temp/time for out gassing

Re: Pretreatment

I have mostly done just steel parts for an old car, and I have to confess. I have never done anything to my parts except bead blasted, used compressed air and a clean brush to dust the parts off and then PC'd them. Does this make me some sort of hack? My parts have been coming out great. I suppose I am just lazy. lol

Re: Pretreatment

Be very careful about the paint thinner for cleaning because most solvents are oil based. I would use isopropyl.

I usually blast, dip for a few sec's in muratic acid (diluted) wash off with water, dry, and wipe down befor shooting with acetone..
