ing is a process that involves applying an extremely durable plastic

coat

ing using an electrical charge and compressed air before baking it permanently with heat typically in an oven but heat lamps can also be used using the large 240 volt home oven has many benefits when

powder

coat

ing not only can you fit large parts like wheels and home ovens but they also recover much quicker allowing the oven to get back to curing temperature faster and giving you the best results its durability is what makes it so popular for parts on the underside of a car that are commonly hit with stones are sawed it's also great for hood hinges or suspension components like Springs and items that move and stretch because it's more flexible than paint

powder

coat

ing is much safer for the environment than paint because it contains no solvents that produce hazardous emissions or VOCs which also means cleanup is quick and easy and leaves you with no hazardous solvents to dispose of just sweep up your floor and blow out the gun and everything is clean which is also much easier than cleaning a paint gun let's discuss the process an emitter rod electrically charges the air in front of...

the gun compressed air moves the

powder

out of the gun where it passes through this charged air and picks up a high voltage electrical charge as these charged particles travel through the air they're drawn to the metal parts which have been grounded by being attached to the ground lead of the

powder

coat

ing gun the electrical attraction is how the

powder

particles are able to get great coverage and reach inside parts and around edges unlike paint which travels in a straight line out of the gun this is also why you need a good ground to attract the

powder

for the best coverage so impossible ground directly to the part you're spraying another advantage of

powder

is that if you make a mistake you can simply blow the part off and start again which is a huge advantage of our mistakes that are made during the painting process now once the part is

coat

ed you'll place it in the oven to cure during this process the first thing you'll see is the flow out or melting of the

powder

particles you'll be able to see this happen as the

powder

becomes a smooth even surface if it's a gloss it will start to shine at this point a good rule of thumb is to allow the

powder

to flow out and then continue to cure it in the oven for an additional 20 minutes at 400 degrees Fahrenheit but remember to check the instructions for the

powder

you're using a great tip that's more accurate is to use an IR thermometer to check the temperature of the part rather than the...

temperature of the air in the oven when the part reaches 400 degrees then cure it for 20 minutes also heavier cast parts will absorb more heat and may take more time to reach the full cure temperature which is another reason it's beneficial to use an IR thermometer and remember an extra five to ten minutes of curing shouldn't hurt the

powder

let's discuss safety when spraying

powder

you'll want to wear safety goggles and a dust mask cure the

powder

in an electric oven dedicated for

powder

coat

ing don't cook in the oven after you've used it for

powder

coat

ing and never use a gas oven to cure the

powder

when cleaning up never use a vacuum cleaner which could emit a spark and ignite the

powder

always sweep the

powder

with a soft brush and dustpan also never smoke near the

powder

when filling the gun applying the

powder

or when cleaning never touch the emitter rod to defuse the possibility of an electric shock touch the end of the ground clamp to the emitter rod and remember never handle or touch apart while

powder

is being applied because you could receive an electric shock to begin

powder

coat

ing make sure you remove anything that could be damaged by the 400 degree temperature that is needed to cure the part like grommets bushings bearing seals or other plastic components the part should then be prepped like you would for paint removing all dirt dust grease and oils with a product like

Eastwood

pre paint prep and then wipe with a quality tack rag you...
will also need to remove any old

coat

ings like paint since many paints won't withstand the curing temperature paints will also not conduct a charge which means the

powder

won't adhere properly a great way to remove paint and prep the part for

powder

is by blasting in a cabinet or with a pressure blaster we put the head cover in the

eastwood

blasts cabinet and use glass beads to fully clean the part we used our large cabinet but if you're only doing small parts

Eastwood

offers other sizes of cabinets including a bench top version that's great for small parts or even crafts if cleaning apart by blasting it's a good idea to place the part in the oven and heat it until it reaches 100 degrees this will remove a charge you may have created while blasting that could affect your coverage you can also use a chemical stripper like

eastwood

down the metal to remove these

coat

ings which we've done with other projects like when we restored an old set of wheels and covered them in East with gloss white and cosmic clear if your

powder

coat

ing a cast part it's also a good idea to place the parts in a 450 degree oven for an hour to bake out the impurities and the IR thermometer is helpful for determining the temperature of the part if it's preheated or being hot flocked an IR thermometer will tell you the exact temperature of the part you're

coat

ing while the oven thermometer will read the air temperature and there could be a difference between the two...
especially if it's a thick cast part and here are a few more things to look for many body fillers won't with stay in the hearing temperature and fillers that will withstand the temperatures are not electrically conductive so they will not accept the charge

powder

and we'll leave you with bare spots wherever there's body filler so make sure all body filler is also removed you should also avoid touching the parts with your bare hands because you will introduce oils to the part which will also affect

powder

adhesion parts can be hung to be

coat

ed or placed directly on the rack hanging the parts from the oven rack is a great method if you need to

coat

all sides of the part if using a larger home oven you can support the oven rack with two sawhorses this is easier than attempting to

powder

coat

the part and then hang it on a rack that's already inside the oven here's a tip when

powder

coat

ing a part that has threaded holes use bolts not only to protect the threads but to also give you an anchor point to hang the part when hanging parts make sure you're using wire that doesn't have an anti rust

coat

ing that could prevent proper grounding stainless wire is great for hanging parts when applying

powder

if a part is bumped or touched before it gets to the oven you can blow the

powder

off and start over this is one huge advantage over paint where you would be forced to use a chemical stripper to remove the paint before respraying if you need to...
mask areas be sure to use a quality high temperature polyester or fiberglass

powder

coat

ing tape polyester tape is much thinner than fiberglass tape and provides a sharp or cleaner edge but fiberglass tape is more flexible and will conform to irregular shapes better to protect this engine head cover off a ski-doo snowmobile we're using the high temp polyester masking tape to get a nice edge around the cover use the narrow tape on the lip and then use the wide tape to cover the entire bottom with a cover flipped over use a razor to cut along the edge also tape off any other surfaces you don't want

powder

coat

ed and trim with a razor if you need to tape off a large area you can use aluminum foil in conjunction with high temp masking tape this way you can protect your parts while using less tape high heat silicone plugs can be used to cover and fill any holes to begin

powder

coat

ing select the

powder

you'll be using and pour it into the cup for this project we're using

Eastwood

metallic blue

powder

which will really make it pop when using

Eastwood

dual voltage system and for best results it's recommended that for the cup not to be filled more than half whey

powder

is made of my new particles so different colors cannot be mixed together like paint to create a new color here's a tip make sure you're using virgin

powder

so you know it's pure and doesn't contain dirt or contaminants

powder

can be swept sifted and reused but for the best results...
use virgin

powder

like we offer at

Eastwood

it's now time to connect the ground clamp and begin spraying the

powder

hold the gun about 8 to 16 inches from the part and apply using gentle steady sweeping motions while moving around the entire part the gun we're using only requires 5 to 10 psi at a mere 2 CFM which is why you can use a small pancake compressor apply

powder

until the part is uniformly covered and you can't see through it a dual voltage gun like this one from

Eastwood

is great because you can switch the voltage to get the best coverage on large flat areas as well as in tight corners where you can get poor coverage due to the Faraday cage effect meaning the

powder

will be repelled from those areas unless you're using a gun that allows you to adjust the voltage Faraday cage effect happens most often in areas where the angles are about 90 degrees or tighter to avoid this effect first set the

powder

gun to the lower voltage setting to limit the charge or building up on the part make sure you have the deflector on the gun and turn up the air pressure to allow more

powder

to flow out of the gun also spray these areas first because by spraying them first you haven't built up as much of a charge which will repel the

powder

start spraying the area with a gun parallel to the part and the deflector will direct the

powder

out of the side and onto the part once you spray the tight areas you can remove the deflector and switch the gun back to the higher...
voltage setting to spray the remaining larger areas once the

powder

is applied place the part in the oven and cure we suggest curing the

powder

at 400 degrees Fahrenheit once the

powder

flows out and appears to be smooth continue to cure for an additional 20 minutes remember always check the instructions for the

powder

you're using for proper curing temperature and time when it's fully cured remove it from the oven and you'll have a highly durable part that looks great for years to come as you can see the

Eastwood

blue metallic really made this old snowmobile headcover look better than it was when it was new and the best part is that it didn't take my investment or time to get these results if you want to add a cool effect you can sand through the lettering to give it a two-tone appearance start with 120 grit and then move to 600 800 and finally 1200 grit to remove all the

powder

as well as the scratches from the previous grits of sandpaper with the

powder

from the lettering removed the cover looks even better and it only added a few additional minutes of work as you can see the blue metallic looks awesome against the aluminum lettering giving it a cool two-tone effect plus we now have a highly durable

coat

ing that will look great for years to come to clean the gun simply blow it off with your blow nozzle no harmful chemicals or solvents to dispose of like when mixing and spraying paint not only is

powder

coat

ing easy to apply it's also easy to clean up...
even from a floor in fact all you need to do is sweep up the overspray that's why when you're buying

powder

you should make sure you're buying virgin

powder

many companies who sell

powder

sell reclaim

powder

which is why it may cost a little less but you may not be getting the best

powder

and it may show up in your finished job now that you've seen how easy it is the

powder

coat

let's go over a few other options chrome

powder

s can mimic the appearance of chrome but typically need to be clear

coat

ed for highest durability there is a trade-off for this added durability because you will lose some of the chrome appearance additives like metal flakes can also provide a great appearance to your

powder

coat

ed items translucent

powder

s can provide a great look and drastically change the appearance whether it's sprayed over chrome or a white base these were sprayed first with white

powder

and then top

coat

ed with a translucent as you can see there's a big difference in appearance whether the base is chrome or white you can even

powder

cook glass using a process called hot flocking which means the part is preheated before applying the

powder

this is done because the glass won't conduct a charge so it also won't attract the

powder

when the part is removed from the oven the

powder

is applied quickly before the part cools and that's because it's sticking through the part because it's hot not because it's attracted due to the static...
electricity you can actually see the

powder

begin to flow out because the glass is so hot hot flocking can also be done on metal objects to help with the coverage especially on a second

coat

the ground clamp is still connected to the metal but you're gaining the benefits of both electrical attraction as well as the

powder

sticking to the due to the heat and remember
