Our Electrophoresis Finish Services
Provide uniform coating thickness (10-30μm) with 98% edge coverage for metal components. Our automated cathodic electrophoresis line achieves ≤5μm thickness variation, offering corrosion resistance up to 1000+ salt spray hours (ASTM B117).
What is Electrophoresis Finish?
An electrochemical deposition process where:
1.Charged paint particles (20-50nm) migrate in DC field (50-400V)
2.Components become deposition electrodes (cathode/anode)
3.Cured films form cross-linked polymer networks
Key characteristics:
Process types: Cathodic (CED) or anodic (AED)
Curing: 160-200°C for 20-40 minutes
Film properties: 3-8H pencil hardness (ASTM D3363)
