Powder Coat Removal
Removing powder coating can be an extreme challenge. It usually involves very caustic and hazardous chemicals, or industrial size ovens that heat to 1,000 degrees. Sand blasting is also an option, but not a good one since it takes about 30 seconds for every square inch of powder coating to be removed. According to most powder coating experts, chemical stripping is the "easiest" way. Below we will compare Dustless Blasting with chemical stripping.
Removing Powder Coat with Chemical Stripping
Though chemical stripping is widely regarded as "by far the easiest way to remove powder coat", it has a number of disadvantages. This process involves dipping powder coated parts into a large vat of a toxic, hazardous chemical which has a high concentration of methylene chloride. The parts must remain in the vat until the powder coating has been chemically burned off.
1. Put on elbow-length chemical resistant gloves and safety goggles.
2. Submerge the powder coated part in the chemical vat.
3. Jostle and stir the part around occasionally to help schluff off the powder coating.
4. Wait for the powder coat to chemically burn off.
5. Once the powder coat is gone, you must rinse the part with tri-sodium phosphate.
6. If you don't have a tri-sodium phosphate dipping tank you can rinse the part with water, however, the water won't remove all of the methylene chloride. It is then a good idea to heat the part in a burn-off oven to evaporate any remaining methylene chloride.
• It's Dangerous
• It's Expensive
• It Smells Horrible
• It Burns Skin on Contact
• It's slow in cold Weather, Vat Must Be Heated
• Must Wear elbow-length chemical resistant gloves
• Chemical must be stored in an HDPE container with lid
• Must rinse in additional tri-sodium phosphate dipping tank or burn off remianing methylene chloride in an oven.
Removing Powder Coat with Dustless Blasting
Dustless Blasting is the simplest, fastest, and most environmentally friendly way to remove powder coating. It involves no toxic chemicals, and uses environmentally neutral recycled glass abrasive mixed with water. The water in the Dustless Blasting process cools the powder coat, making it brittle, which allows it to erode away quickly and easily.
1. Put on safety glasses and ear plugs.
2. Aim the blast nozzle at the powder coat.
3. Depress the deadman and watch the powder coat fly off.
4. Rinse the part with rust inhibitor and water.
• You don't get to feel like a mad scientist with Vats of dangerous chemicals
