Powdercoating question

[E-man930]

Guys,
Can the grey oil cooler duct and the grey alternator air duct cone be safely powder coated without any warping or melting of the parts? (car is an 86 930) The powder coaters were not to sure and I thought I would ask before messing up any parts. Thanks in advance... (If needed I can post up a pic of the parts in question)

No

Those parts are plastic and cannot be powdercoated.

Thanks guys - I'll paint them instead

I sincerely suggest you find different powdercoaters , if they are that unknoledgable about their own profession.

Powder coating is electrostatic painting .....*METAL ONLY :

" "How does it work?"

We use a specially formulated Polyurethane Enamel paint that is mixed with a catalyst and given a positive charge by a transformer. The *METAL object to be painted is then grounded by attaching a wire from the spray unit. The paint is then drawn magnetically to the item being painted with a 98% transfer efficiency. This system allows us to paint *METAL items "

You could use some POR15 to paint them. Stop Rust POR15

Even though it's a rust preventative paint it work very well on fibre glass.
It strengthens the fibreglass and is dries to a finish very similar to powder coating.

The most common primer for fiberglass when using a powder coat finish is some formulation of iodine solution applied thinly by spraying or dipping the object in it. The iodine mixture promotes conductivity so that the electrostatically charged powder coat particles will be uniformly attracted to the object or part being coated.

Once the primer is uniform and set, but not necessarily dry, the finish powder coat can be sprayed onto the object in multiple coats as needed to achieve desired texture and finish.

Once coated, the object is heat cured in an industrial ultraviolet or infrared oven at between 300 and 400 degrees Fahrenheit, according to particular powder coat manufacturers' instructions. Once cooled, the finish is hardened and more durable than a liquid paint finish.

peehonix,

thx for the headsup. I did not know non metel pieces could be powder coated if you prepped them with the right pre-coating. So my comment before about the ability of E-man930's PC'er might not apply

My powdercoaters are the best in the state... They have almost anything you can think of, that said, I just wasn't sure (neither were they) of the melting point of said plastic items. I ended up using 500 degree engine enamel paint that almost matches the factory grey. turned out really nice, now just waiting on a carbon shroud.
