Powder coating is typically for metals and not ceramic materials. To apply a ceramic coating, a different process is used that involves spraying a ceramic-based solution and then curing it at high temperatures. Here's how you apply a ceramic coating:
- Prepare the part: Thoroughly clean and degrease the ceramic item. If necessary, lightly abrade the surface to promote adhesion.
- Dry the Part (Optional but Recommended): Place the cleaned part in an oven and heat at approximately 450°F (232°C) for 30 minutes. This step ensures complete dryness and can improve coating adhesion.
- Spray the Ceramic Coating: Use a High Volume Low Pressure (HVLP) or touch-up spray gun with a 0.8 mm tip to apply the ceramic coating. Ensure even coverage by maintaining a consistent distance and speed. Apply thin, even coats to avoid runs or drips.
- Cure the Coating: While the part is still warm (if the drying step was used), cure the coated part in an oven at 500-700°F (260-371°C) for 60 minutes. Refer to the specific product's instructions for exact temperature and duration, as they can vary. This curing process hardens the ceramic coating and bonds it to the substrate.
