๐ Electrophoretic Coating (E-Coating): Uniform Protection with Style
๐งฉ What Is E-Coating?
Electrophoretic coating, or e-coating, is a surface finishing process that uses electrical current to deposit paint particles onto a conductive substrate. It offers excellent corrosion resistance and a smooth, uniform finish.
๐ Process Workflow
- Pretreatment โ cleaning and degreasing
- Phosphating โ optional adhesion enhancer
- E-Coating Bath โ immersion in water-based paint
- Electrodeposition โ electric charge attracts paint particles
- Rinsing โ removes excess coating
- Curing โ baking for durability
