All rights reserved. Powder Coating. Written by Molly. May 24, The most common methods to remove powder coating are: Chemical stripping Burn-off in oven Media blasting 1. Chemical Stripping Chemical stripping methods can go by several names. Considered dangerous and hazardous Chemical stripping also has disadvantages. Does not inherently leave an anchor profile One final thing to consider is the desired anchor profile of the surface being stripped. Burn-off in Oven Thermal removal methods use very high temperatures to burn off powder coating, which turns to ash and must then be washed off.

Requires lots of power Not only is the required equipment expensive, but supplying the necessary power is even more costly. Can warp and damage parts The extremely high temperatures required to remove powder coating may warp or damage parts. Wet vs. Previous Story. The sandblaster will require the use of an air compressor to deliver that high-pressure air. Keep in mind that air compressors, even used ones, are not cheap—you may want to try getting by with a smaller compressor if you can.

The air must be dry, as well—otherwise, the media will mix with the moisture, and that will cause clogging in your gun. Steel grit is one of the lowest cost blast medias when used in a blast recovery system as it breaks down less than about any other blast media allowing 60 — uses before needing to be replaced.

Steel grit will work about as fast as aluminum oxide for powder coating removal which between its speed and cost makes it a great option. While the first two blast medias are primarily designed for blast media recovery systems or blast cabinets , if you will not recover your blast media you may consider crushed glass.

A fine to medium crushed glass will remove powder coating rapidly. In addition, crushed glass blast media will tend to not hit the surface as aggressively leaving a slightly smoother finish to the product surface. Another blast media that can be used either in a recoverable way or expendable is garnet. Garnet tends to be fast and efficient but can be harder to get compared to crushed glass media depending on where you are located. Ultimately the blast media you select will have a big impact on how fast you can remove powder coating.

If you will be recovering your blast media aluminum oxide will be fastest while steel grit will be fast but a bit more cost effective. If you will not be recovering the blast media then the crushed glass is a great blast media for removing powder coating. Siphon Feed VS. Pressure Pot Sand Blaster? The best media for sandblasting is not sand.
