Creating a current for high temp plastics

[John_Henry]

Had a quick question,

If I am powder coating high temperature plastic automotive parts, like intake manifolds, etc..., will there be enough current for the powder to cling to the part or will it resist the current because of it's polymer base?

The reason I ask is due to the fact that I have seen some plastic intake manifolds done, but couldn't figure out what current they are using or how the process was preformed.

Thanks guys

no, it can't effectively be grounded. stick your part in the oven at 225 or so then pull it out and shoot it hot. the powder will melt on contact and stick that way.

No you will not be able to do them cold as the plastic is a insulator and the powder will not be attracted to the part. You must hot flock on these kind of parts. That being said if you happen to have the Columbia Coatings Hyper Smooth with the Multi Coat tip then you can do them cold no problem. That is the only way I know of to do them cold. just be careful when hot flocking or you will get runs if you apply to much powder.

Sweet,

Thank you again gentlemen for your wise words.

I watched that video on the hyper smooth mulit coat nozzle and i just think its a gimmick. I can't see how it could disperse THAT much different than any other gun. Anyone have any first hand experience?

I just happen to have first hand experience and I promise you that it is no gimmick! If you happen to be around NW Georgia you can come by my shop and I will be happy to show you what it will do (that offer stands for anyone else also). It absolutely does everything as advertised. It will lay powder on ANY material at room temp. no hot flocking required. I have even coated tile for a shower with this attachment. It lays the 12th coat on just like the 1st! I just cant say enough about this tip it makes life so much easier for me.

I am in Menlo, Georgia. It would be about 3-4 hours from you location I believe. If you are ever out this way feel free to drop in anytime.

i know this isn't a hypersmooth thread, but i have to concur w/ ty. i haven't used it as much as he has, but i have put 8 coats on a wrench, cold, easy. i messed around w/ some other materials to see if it would stick (didn't bake any of them) and it seemed to stick to all.

not sure how it works, but i have an idea from studying the nozzle closely. it doesn't look like much, that's for sure.
