When it comes to powder coating stripping, remaining prepared is the key. Powder coating is a great way to protect the metal from rust and other environmental elements. However, it can be tough on your paint job if you don’t know how best to remove powder coatings‘ old surface before removing a new one- make sure that any previous protection has been removed first!
This guide will cover different methods for stripping or sanding down existing layers of finish. Hence, they’re ready when applying fresh PVC electrolytes to provide long-lasting durability without sacrificing aesthetics too much.
Option 1: Sandblasting
Sandblasting is a great way to remove powder coating, but it also has some limitations. The pros of sand-based destruction include that you don’t need expensive disposal fees like those associated with chemical strippers, and there’s no environmental impact since all debris materializes into its pile at your feet.
Additionally, sandblasting will create a profile while removing the existing coat of powder. This can reduce two common steps for removing the coating, then profiling and cleaning part to just one step – stripping any existing powders from surfaces with media that often have more uses than originally planned. The potential drawback is the cost compared to chemical stripping or batch burn-off ovens, but this may not always be true depending on how much work needs to be done in preparation beforehand. Some other drawbacks include:
- Sandblasting is a great way to remove powder coating quickly from surfaces with recessed areas, but it’s not always the best option.
- It may be more cost-effective in some cases to hire a professional instead of owning the equipment.
- Media savings and reduced disposal fees are only worthwhile if you have enough space to store your largest parts in a sandblast room.
· Sandblasting might take more time than ovens.
Option 2: Solvent Chemical Strippers
Another method of powder coating stripping is to use solvent chemicals. Chemical stripping is an excellent way to remove powder coating from any surface, especially if you have difficulty removing it by hand. The chemicals are quick and easy because they only take minutes before the part can be cleaned with water or another cleaner agent depending on what your manufacturer recommends for best results.
Chemical stripping can be useful when you need to strip away excess material that has built up on your part or if there are some pesky blemishes from previous coats of paint inhibiting smooth functioning – like rust spots! However, these hazards make this process best suited as an option in select circumstances only because regular use will inevitably result in greater wear and tear over time.
Option 3: Burn Off Ovens or Heat Gun
Removing powder coat with heat gun or burn off ovens is also a method of powder coating stripping. Batch burn-off ovens are one of the fastest ways to remove powder coating from parts. They have low disposal fees, an easy-to-use setup process, and can be used on most surfaces without issue.
However, they do come at a cost due in part because you need large enough ovens for any given product, which may require initial investment before generating income through sales or usage fees. Additionally, with these methods, there’s still plenty else that goes into preparing whatever surface will eventually receive new coatings, such as sanding down rough edges if necessary.
Batch burn-off ovens can be a great option for those who regularly need to remove powder coating, and they’re best if you have high production because, in line with your system, these work quickly.
