How To Remove Powder Coat From Aluminum Wheels
If you've ever tried to strip an object that has been pulverization coated before, yous know it can be stubborn. Durability is a major benefit of powder coating merely also makes it a pain to remove, leaving you to wonder how to remove powder coating hands.
Powder coating can exist removed using chemical strippers such as Benco B17, heat, abrasives (sandblasting with new media), or lasers. Each method has its advantages and disadvantages that y'all'll need to consider when choosing which to use.
In this article, we'll discuss the main methods that you tin apply to remove powder coating. Also as the pros and cons for each, rubber precautions you should take, and what supplies you'll demand for each method.
Methods How To Remove Pulverization Blanket
Powder coating uses an electrostatic accuse to comprehend every inch of an object. It's so effective that it can be hard to remove.
In that location are iv main ways to remove powder coating, which will be covered in-depth in this commodity:
- Chemical strippers
- Heat or thermal removal
- Abrasive blasting
- Light amplification by stimulated emission of radiation removal
Why Would You Need To Remove Powder Coating?
Fixing mistakes. If you've merely started pulverization coating yourself, you're bound to brand errors. On your first few tries, your blanket might not come out as good every bit you'd hope for. And then y'all'll desire to exist able to remove the powder coating to attempt over again.
Refinishing. If you have an erstwhile piece of metal, you might simply want to refinish or update information technology to keep information technology looking shiny and new.
Cleaning. After you're done pulverisation blanket, you'll need to strip your cleaning hangers and racks or they will just keep edifice up with thicker and thicker coats each time you complete some other job.
Chemic Strippers
When it comes to removing powder stripping, your get-go pick is to use a chemi cal stripper.
A great powder coat chemical stripper you may not exist enlightened of is Miles Remove 9000 you can get more details here (dipping awarding) or Miles Remove 9001 a gel version (applied with a bristle brush). Both are great for powder coat removal from as quick as 15 minutes – two hours or overnight depending on the type of coating being removed. It is Eco-friendly and excellent for job re-work as it can be re-used and even diluted when heated, saving you money!
The best part virtually Miles Chemic stripper remove 9000 and 9001 is they are non-toxic
If y'all are looking for innovative powder coat removal/strippers that volition work with a variety of applications including stubborn rims and aluminum wheels cheque out the Miles 8659 Gel or Miles 8660 liquid here. The 8660 tin can be diluted with water, to salvage even more than, when in heated tanks and are a great culling to the caustic Benco products which are now hard to get.
NOTE: The Miles 8659 gel and Miles 8660 are a little more than ambitious and take a mild acid to assist accelerate performance and do crave D.O.T. shipping equally a corrosive liquid. They do not burn the skin upon accidental contact but due to the low PH require D.O.T. shipping.
All of the Miles products can too be shipped to residential addresses.
In that location is a whole range of chemical strippers available from home improvement retailers like Home Hardware and Lowes. There are many different types of chemicals to cull from which have various applications, so it'due south important to choose a stripping product that meets your specific needs.
Paint stripper (sometimes called aircraft stripper) is another example of a chemic stripper y'all can become here on eBay at an economic price. Information technology has a pretty wide range of applications and is suitable for use at home, so it can be a great place to start. Although more than stubborn powder blanket might not come off with a basic pigment stripper.
This option is slap-up for DIYers who are just doing projects in their backyard and might non have the equipment needed for some of the other stripping methods.
Oven cleaner is another chemical that can strip some types of powder coating and is cheap and easy to go.
Y'all can get chemical strippers in i-fourth dimension-apply droplets cans or gels. They usually will need to be practical multiple times to get the job done.
Now that products containing methylene chloride are existence more regulated past D.O.T. for shipping, newly developed products are coming on the market like the Miles 8659 and 8660 listed above. These new products are Depression VOC, environmentally friendly strippers, and are more economically feasible methods to recycle paint rework.
Be especially careful with what products you employ on pulverization-coated aluminum. Some chemicals similar caustic soda are very effective at cleaning steel and iron but will destroy aluminum.
Chemical Stripper Pros
Using chemicals to remove pulverization coating will leave you lot with a uniform surface later yous've removed the coating. Some other methods like sandblasting can scratch or remove tiny pieces of metal. If y'all're not re-coating the surface y'all'll probably desire information technology to be shine and shiny without scratches.
Chemical strippers are cheap and available in small quantities. They're great for a i-time job or for someone who doesn't need to remove pulverisation coating very oftentimes. They are also available in majority for more than frequent and larger jobs.
Chemical Stripper Cons
Chemicals used to remove pulverisation coating can be really bad for the environment and have strict requirements on how to dispose of them.
Chemical strippers besides don't leave a profile for a new coating of paint to stick to. If yous're planning to re-coat the metal you're stripping, you might desire to sandblast it instead. The scratches and marks from the adhesive make information technology easier for many types of paint to stick to metal.
How To Work With A Chemical Stripper Safety
Working with chemicals that are capable of melting powder blanket off of metal tin be dangerous. Even a pocket-sized driblet will burn your peel, and getting it in your eyes can cause permanent harm.
Take the prophylactic warnings seriously and wear the proper equipment.
You'll desire to wear thick safety gloves , ideally elbow-length. It's all-time to get a inexpensive pair and immediately throw them away when you're done, rather than trying to clean them. Otherwise, yous risk getting the chemic on your skin after you've taken your gloves off.
Eye protection like goggles is also a must.
A heavy-duty frock will help protect you in instance of whatever spills or splashes. Wearing long sleeves is a skillful idea too.
Finally, proper ventilation is required likewise. Many strippers contain unsafe chemicals that could crusade cancer or make you pass out if you're breathing them in a closed room. You might want to vesture a total-face respirator when handling these chemicals if yous've got 1.
Make sure to proceed any small kids or animals out of your workspace while you're using chemical strippers equally well.
You might demand to utilize a flake castor to aid scrape the pulverization coating off your object in one case you've applied a chemical stripper. Be careful not to fling stripper around when doing this.
Using A Chemical Stripper – Steps To Follow
1. Do a spot examination first
You'll want to offset off past spot testing your item with your stripper to make certain information technology volition piece of work. Utilise a small amount of the stripper by following the recommended instructions. Then effort to scrape off the powder coat with a scraper.
If the blanket comes off fairly easily, you can go alee and utilize the stripper to the unabridged object. If the coating is nevertheless actually stuck on, you tin spot examination another area and give it more time. Or y'all might demand to become a stronger product if information technology notwithstanding doesn't work.
2. Utilise your stripper
Glaze the entire part in the chemical stripper. Let it sit down for the same amount of fourth dimension that you used for your successful spot test.
three. Scrape the blanket off
After enough time has elapsed, it's time to clean the pulverisation coating and solvent off. You tin can use a bladed paint scraper or a chipping brush for this step to commencement with.
Once almost of the coating has come up off, yous can go over the metal again with steel wool or an annoying pad to get any remaining coating off.
If you lot're struggling to get all of the coatings off, you lot might need to re-use the chemical stripper and wait over again.
iv. Wash your part
Rinse your stripped part off with water and detergent to remove all remaining traces of coating and chemicals. Make sure to dispose of the removed coating carefully.
Stronger Chemical Strippers For Larger Jobs
Virtually of what I discussed above regarding chemic strippers is aimed more at DIYers and hobbyists.
If you demand to strip powder coating off big numbers of pieces or you merely desire to practise it faster and more efficiently, I'd recommend a stripper that'due south designed for more than industrial applications such equally Benco B-17 or 1010P.
Benco B-17 Industrial Liquid Stripper
Tin strip about 3mm of pulverization blanket in less than 20 minutes. It contains stronger and faster-interim chemicals like methanol chloride, phenol, and hydrofluoric acid that aren't establish in retail strippers.
1010P is less powerful than B-17, merely will even so piece of work ameliorate than anything you can buy at your local hardware shop.
Be aware that these industrial chemicals can unremarkably only be ordered in larger quantities – such as 5 gallons, xxx gallons, or 55-gallon drums. So they're really only a expert solution if you own a shop and will be stripping powder coating on a regular footing.
Y'all will too need a container to exercise your stripping in unless y'all intend to strip items in the drum it was shipped in.
You'll need to be extra prophylactic when handling industrial-strength chemical strippers. They can remove powder coating faster than retail strippers, but that ways they can do real harm to your pare if not handled correctly too.
Benco B-17 stripper costs about $200 for 5 gallons. Although many companies will no longer ship it to residential addresses since it'due south considered a chancy production.
Method Ii – Heat or Thermal Removal
Removing powder coating using heat is safer and less risky than using chemicals. They break down the powder coating into ash that tin be hands washed off.
In that location are a few different methods you tin can use: a bake-off, burn down-off, thermochemical, or fluidized bed system. Each ane uses different temperatures. Generally, the college the oven temperature, the faster the coating will come off.
Thermal removal methods aren't really practical for pocket-sized shops or DIYers since yous need specialized ovens.
Bake-off. This method uses temperatures of 650 – 750 degrees Fahrenheit and will take about three to 6 hours to clean off pulverization coating. Later baking, you need to wash the pulverization blanket off then that it doesn't re-stick to the metal surface.
Fire off. This method uses temperatures of 1000 – 1200 degrees Fahrenheit. All powder coating gets removed in just a matter of minutes at such high temperatures. It's difficult to do this at home, and it's usually only used in production facilities that need to remove large quantities of powder coating.
Fluidized bed organization. This method uses something abrasive similar sand that has been heated up to around 800 degrees Fahrenheit which is rubbed against the product to strip the pulverisation coating off. It'due south kind of a mix between a thermal and abrasive method.
Thermochemical. Uses a mixture of chemicals and loftier temperatures to strip blanket. Commonly done at temperatures of 800-900 degrees Fahrenheit.
No matter which thermal method you employ for removing powder coating, information technology's important to make sure that hangers and racks used can resist the high temperatures used. For example, soldered joints or parts fabricated of magnesium won't work since temperatures tin reach 1,000F or higher.
All of these methods create byproducts called VOCs or volatile organic compounds. These need a special exhaust system with afterburners to destroy.
Heat Removal Pros
Using a heating system is fast and efficient. It's smashing for doing big volumes of stripping.
When washed correctly, thermal processes release nearly no contaminants back into the environs, dissimilar chemical strippers.
Estrus Removal Cons
The equipment used for thermal stripping consumes a lot of energy and can be expensive to purchase. They can hands cost thousands of dollars.
Some rut removal methods need a wash phase to remove burnt powder after they've been processed.
Whether you utilize electricity or natural to power your ovens, they will result in a high utility bill.
The high temperatures used to mean you lot take a chance altering the shape of the underlying metal. Heat removal also doesn't get out a profile for the new paint to adhere to, similar to chemical stripping.
Method Three – Abrasive Blasting
Abrasive blasting (sometimes called mechanical removal) uses abrasive media similar sand which gets shot at the pulverisation coating surface at high speeds. This strips the coating of the metal'due south surface.
To utilize this method, you'll demand a sandblast cabinet. Sandblast cabinets come in ii primary types, pressure and suction. For removing pulverization coating it's all-time to use a pressure level sandblast cabinet. It'due south better at removing the stubborn pulverization coating.
If your object is too large to fit in a sandblast chiffonier, you'll need to set up a sandblast room or tent.
You lot tin can't simply utilise abrasive blasting in your garage. The abrasive media will get flying beyond the object yous're stripping and impairment anything else in its path.
Abrasive Mediums
Depending on how thick your layer of pulverization coating is, you'll desire to consider different abrasives. Lighter abrasives similar glass beads will work if the blanket is lite. Only for thicker coatings, you lot'll want something more aggressive like steel grit or aluminum oxide.
Other abrasives include:
- Sand
- H2o
- CO2 pellets
- Garnet
- Dry ice
- Slag
- Plastic Media
Picking the right media affects the contour left on the metallic'due south surface, as well as how fast it works. The more aggressive a media you cull, the faster it volition make clean but it volition also leave the roughest surface on the metal.
Abrasive Blasting Pros
Using abrasives is fairly inexpensive if you're doing it on any kind of scale. The equipment is much less expensive than using ovens. It can be good for smaller shops between what a DIYer needs and what a large-scale industrial operation would use.
Abrasives are also a portable pick. You can use a modest sandblasting chiffonier or pot to remove powder coating in the field.
Using abrasives leaves a surface contour, which makes it easier to utilise some paints and coatings.
Abrasive Blasting Cons
Abrasives can be a bit slower than a stripping method. It unremarkably takes about thirty seconds for each foursquare inch of powder coating that you want to strip away.
Each part you want to strip has to exist blasted individually, which means higher labor costs.
Parts that have irregular shapes can be difficult to blast and can trap abrasives, potentially causing problems with future coatings if not fully removed.
Abrasives are skilful for steel and harder metals, but they can erode softer metals like aluminum.
Method Four – Laser Removal
Big scientific advancements take been made when it comes to removing powder coating. At present you tin even practice it with especially-designed lasers!
Lasers work by called-for powder blanket off of metal, similar to the employ of ovens, just in a significantly more directed and focused way.
Light amplification by stimulated emission of radiation Removal Pros
Lasers are very precise and can strip pulverization from a pocket-size area, but they tin exist used for large surfaces too.
They can be used on about whatever textile since they don't alter the substrate underneath the pulverization coating. The heat of the laser doesn't touch the bodily surface of the metallic while stripping, which makes it perfect for aluminum.
Lasers have little to no impact on the environment.
Laser Removal Cons
As you lot'd imagine, lasers are pretty cutting-border technology and they can be very plush to buy. For that reason, lasers are only really applied for stripping in a production environment.
Like all of the other methods except abrasives, laser removal doesn't exit a contour on the metal's surface, meaning extra steps might be needed earlier re-applying pigment or another powder coating.
Which Powder Blanket Removal Method Should You Utilise?
Which method you use will depend on the quantity of removal y'all need to do, your substrate, and the results you lot want. Hither are some recommendations based on dissimilar needs though:
For the lowest price. If you're only stripping once or twice per year, picking upwards a can of a chemical stripper from your local hardware store is probably the cheapest option. For more regular powder blanket removal, abrasive blasting is the cheapest.
For the fastest removal. If yous need a part cleaned quickly, a fire-off arrangement is the way to go.
To minimize environmental impact. Lasers are the about environmentally-friendly stripping method, followed closely by thermal stripping. Avert chemicals if there are environmental concerns.
For dingy or greasy parts. If you're dealing with parts from engines or other equipment that comes in contact with oil and grease, thermal stripping is best. It volition burn down away all of the impurities along with the powder coating.
For steel parts. Abrasives work quite well on steel since it's strong enough to
For delicate parts. Lasers are best if your item can't withstand high heat. Chemical stripping is a more affordable option if y'all only need to clean a few pieces of aluminum.
For wheels and rims. Normally a combination of sandblasting and chemic stripping is used when you demand to remove pulverization coating from rims and wheels.
Conclusion
Removing pulverization coating yourself can exist a lot of work.
To figure out what method you lot'll use to remove pulverization coating, you should consider a few things like the book of powder coating removal you need to do, besides every bit the type of metal yous'll be stripping.
If you merely need to remove pulverization coating once or twice a year, it's probably easiest to simply buy some commercially available chemic stripper.
For small shops or a hobbyist who frequently needs to remove powder blanket, using abrasives with a sandblast cabinet tin can be a good solution.
Bake-off ovens, blast rooms, and big chemic stripping tanks make sense only on larger (industrial) scales for large batches of work.
Deciding the right method for removing powder coating normally involves balancing out the fourth dimension it will have you compared to the cost investment required. Don't forget to Check Out The Eco Friendly Powder Coating Hither
