To prevent rusting under powder coating, it’s important to follow proper precautions and materials handling techniques. Here are some tips on how to ensure your metal is protected from rusting during the coating process:
1. Clean the metal surface thoroughly: Before applying the powder coat, it’s essential to clean the metal surface thoroughly. Use a soft-bristled brush or cloth to remove any dirt, grease, or oil from the surface. Avoid using harsh chemicals or abrasive cleaners, as they can damage the powder coat or create corrosion.
2. Apply protective coatings: To prevent metal rusting, you should apply a protective coating over the metal surface. There are many types of protective coatings available, including polyurethane, zinc-plated steel, and chrome-plated metals. Choose a coating that is appropriate for the type of metal being coated and its intended application.
3. Dry the metal completely: After applying the protective coating, make sure the metal surface is completely dry. If there is any moisture left on the surface, it can increase the risk of rusting. Allow the metal to fully dry before proceeding with the powder coat application.
4. Preheat the air supply: Preheating the air supply can help to ensure that the powder coat coverage is even and consistent. You can do this by running an air dryer or heating the metal surface in front of a fan.
5. Use quality products: Using high-quality products for the powder coat and protective coatings can also help to reduce the risk of rusting. Look for products that meet industry standards for rust resistance and durability.

In conclusion, metal rusting under powder coating can be prevented by following proper precautions and using quality products. By cleaning the metal surface thoroughly, applying protective coatings, drying the metal completely, preheating the air supply, and using high-quality products, you can ensure that your metal is protected from rusting during the coating process. Remember, proper preparation and attention to detail are key to ensuring a successful powder coat job.
