Our Electrophoretic Lacquer Process
Substrate Evaluation & Feasibility
We begin with material compatibility analysis to ensure optimal adhesion and long-term durability.
- Substrate identification (metal / plated parts / engineered plastics)
- Surface condition inspection
- Adhesion feasibility testing
- Coating thickness and finish requirement review
Surface Preparation & Pre-Treatment
Surface preparation is critical for long-term protection.
- Degreasing & alkaline cleaning
- Rinsing & surface activation
- Controlled drying process
- Surface inspection before coating
Electrophoretic Deposition (E-Coating Process)
Using a controlled electro-deposition system:
- Components immersed in lacquer bath
- Electrical current applied for uniform deposition
- Self-leveling coating formation
- Complete coverage including edges and recesses
- Controlled film thickness build (15–25 microns or customized)
Curing & Film Hardening
- Thermal curing in calibrated ovens
- Cross-linking of PU polymer for durability
- Enhanced hardness and chemical resistance
- Controlled cooling to prevent surface defects
Post-Coating Inspection & Handling
- Visual inspection under controlled lighting
- Film thickness measurement
- Adhesion & insulation verification
- Scratch-free handling and packaging
In-Process Quality Checks
- Film thickness control (micron-level precision)
- Cross-hatch adhesion test (ISO 2409 / ASTM D3359)
- Salt spray resistance validation (ASTM B117)
- Electrical insulation testing
- Surface finish & gloss measurement
- Batch traceability documentation
