Cathodic Electrophoretic Clear Deposition (E-Coat) for 4H Hardness
Engineering Overview: Process breakdown of cathodic electrophoretic clear lacquer deposition on brushed brass lock cylinders, guaranteeing uniform 30um coverage.
Technical & Engineering Specifications
| Hardness | 4H Pencil Scratch Resistance |
|---|---|

Cathodic Electro-Coating Science
Traditional spray lacquer leaves thin edges where tarnish begins. Cathodic Electrophoretic Deposition (E-Coat) applies lacquer electrochemically.
100% Edge Coverage
- Immersion Deposition: Water-borne polyurethane particles coat every sharp edge uniformly at 50–100V, providing 4H pencil hardness.
