Powder coating is well known for its adhesion and durability, and is commonly used for automotive parts, construction equipment, offshore platforms, and more.
However, the qualities that make powder coating such a great coating can become big challenges when you need to remove it.
The best method to remove powder coating is Media blasting
Abrasive blasting, which includes both traditional sandblasting and Dustless Blasting, uses media propelled at high speed towards the surface to strip off the powder coating. Dry blasting can take place in a blast cabinet or a blast room, whereas Dustless Blasting requires minimal or no containment.
WET VS. DRY BLASTING FOR POWDER COATING
Traditional sandblasting can be a slow process for powder coating removal, and is not always favored. Because the Dustless Blasting process introduces water, it increases the mass and energy that the machine is putting out, making it dramatically faster than dry blasting. The water also cools the powder coat, making it brittle. This allows it to flake off as opposed to getting gooey, like it does with the heat generated from dry blasting.
THE MOBILE ADVANTAGE
Because Dustless Blasting uses water to suppress the dust plume, the process is environmentally friendly and does not require bulky containment. This makes it perfect for blasting items that can’t fit into a blast cabinet, or can’t be moved. You can even take our mobile units to the customer’s location and blast safely just about anywhere.
SUPERIOR PAINT OR COATING REAPPLICATION
By using different abrasives, you can achieve various anchor profiles with media blasting. As mentioned previously, the correct anchor profile is critical for the reapplication of paint and coatings.
WHAT ABOUT RUST?
The water in the Dustless Blasting process is no problem for metal surfaces, due to our Rust Inhibitor. Simply rinse the metal with diluted rust inhibitor after blasting, and you will prevent flash rust for up to 72 hours. The surface is left clean and ready for the new coating.
There are many ways to remove powder coating. Although Dustless Blasting is our favorite method, you might find that another process is the most suitable for your project.
