Powder coating

My co-worker has a powder coat spray. He told me he'll let me borrow it to powder coat my engine head, rims, and etc... Just wondering if it's safe to use kitchen gas oven for drying.

Industrial ovens have open flames so don't worry about flammable fumes. The next several roasts might have a funny taste! If the powder lands in the oven then it will cure on the oven. I always heard that if one was used for powder coating, not to cook food in it.

I'm not going to use the oven for cooking food. I'm planning on putting an oven in the garage just for the purpose.

frown I guess I can't use our kitchen oven then ..it's gas and we use it for baking..
maybe a toaster oven would do? though I've also heard of special heat/uv lamps could be used as well??

Using gas (natural or LPG) for a powder-oven is no problem as long as you keep following points in mind:

- When using gas, always use indirect heating system e.g. an heatexcanger. This is to prevent the flame residues to come into the oven itself

- For small ovens, especially small chamber type ovens, temperature control with gas is less accurate than with electric heating.

Oven
You must have access to an electric oven or toaster oven other than the one used for food, as mildly toxic fumes are liberated from the powder while curing. Used ovens can be found in appliance centers, news papers, and yard sales. The oven must be in good working condition.

"t is important not to use a gas oven, as the emissions from the coating are flammable." confused

The one I saw was used to coat 4-wheeler racks. It was big enough to drive a forklift in. It had open flames!

I have heard you need a special gun to spray the powder or "electrically" charge the particals to stick to the suface. Does this stuff come in a spray can like spray paint and I can just coat whatever w/ it and put it in the oven?

yeah you have to use a special system

here's a technical explanation... happywink

Quote:

How is the Powder Applied?

The application process involves applying a charge to the dry powder particles and spraying them onto a grounded substrate. The substrate, or part, is typically grounded through the conveyor or hanger holding the part. The powder, once attracted to the part, is then held on the surface until it is melted and cured into a smooth coating film in the bake oven. The spray process takes place inside a booth designed to contain the oversprayed powder and makes it possible to collect the overspray and ultimately reclaim it for reuse.

The powder is fed pneumatically out of the powder container, or hopper, into the powder applicator, or gun. As the powder exits the gun, a low amperage, high voltage charge is applied to the powder particles, causing them to be attracted to the grounded workpiece. This attraction may even cause the powder to "wrap" around the piece, coating the back side.

The oversprayed powder, suspended in the air contained inside the powder booth, is then passed through a separation process that permits the powder particles to be retrieved from the air. The clean air is fed back to the work environment, eliminating the need for air make-up. The reclaimed powder is mixed with a proportionate amount of fresh, virgin powder for reuse achieving consistent results and up to 98% material utilization.

answer to your question laughsilly wink
No they don't make this stuff like a spray can where you can just spray it on and bake... frown


though you could try buying a kit like the one I posted above.. I got mine for around $60 brand new on ebay.. but powder is expensive.. unless you find good deals thumbsup
