Powder Coating Troubleshooting: Color Differences, Discoloration, Stains
Introduction of measures taken due to discoloration caused by gas during incomplete combustion in the drying furnace.
We will introduce troubleshooting for the phenomenon of "color differences, discoloration, and stains," which occurs when colors and patterns differ from the basic color samples or previous painted items. If the issue is caused by the adverse effects on the paint film due to the seepage of rust-proof oil that has entered the welded joint, it can be addressed by wiping off the rust-proof oil that has seeped from the heated joint during water drainage drying with thinner or similar substances. Additionally, there are measures for discoloration caused by gas during incomplete combustion in the baking drying oven. [Causes and Measures (Excerpt)] ■ Due to the adverse effects on the paint film from the seepage of rust-proof oil that has entered the welded joint → Wipe off the rust-proof oil that has seeped from the heated joint during water drainage drying with thinner or similar substances. ■ Discoloration occurred due to overbaking (burning too much) → Follow the recommended baking conditions for each type of powder coating. *For more details, please refer to the PDF document or feel free to contact us.
