E-Coating
Services
Electrocoating (electrophoretic deposition) delivers pinhole-free, ultra-uniform primer coverage on every surface — including recesses, seams, and interior cavities — providing the industry benchmark in corrosion protection.
We primarily operate cathodic ED (CED), the automotive and industrial standard offering superior corrosion resistance and throwing power.
Cathodic E-Coat (CED) — Recommended
The part acts as cathode. Resin deposits with superior corrosion resistance, excellent throwing power into cavities, low VOC. Industry standard for automotive, appliances, and industrial parts.
500+ hr NSSLow VOCFull Cavity CoverageAutomotive GradeAnodic E-Coat (AED)
The part acts as anode. Suitable for aluminium, brass, and zinc substrates where anodic dissolution on steel is acceptable. Used for decorative and lower-corrosion applications.
Aluminium CompatibleDecorativeNon-ferrousE-Coat + Topcoat System
E-coat primer combined with powder coat or liquid topcoat for applications requiring both complete cavity coverage and specific colour or texture finish requirements.
Best CorrosionColor AvailableFull SystemA fully automated, closed-loop process ensuring consistent film build, complete surface coverage, and minimal solvent emissions.
Phosphate Pre-Treatment
Multi-stage zinc or iron phosphating plus DI water rinse creates a conversion layer that maximises adhesion and corrosion resistance under the e-coat film.
Electrophoretic Immersion
Parts fully immersed in water-based paint tank. DC voltage drives ionic resin particles to deposit uniformly on every surface including cavities and welds.
UF Rinse & Curing
Ultrafiltration rinse recovers excess paint. Parts baked at 160–185°C for 20–30 minutes to crosslink the deposited film into a durable, smooth continuous coat.
Inspection & Testing
Film thickness (DFT), salt spray, cross-hatch adhesion, and visual inspection for pinholes, craters, and surface defects per ASTM B117.
Recent e-coating projects across automotive, agricultural, and appliance manufacturing sectors.
Automotive Body Parts
Car bodies, doors, chassis, and structural stampings — e-coat is the OEM primer of choice for complete cavity coverage.
Motorcycle & Bicycle Frames
Tubular structures with internal passages requiring full interior and exterior corrosion protection in a single process step.
Appliances
Washing machine drums, refrigerator cabinets, and HVAC components requiring pinhole-free consistent primer coverage.
Agricultural Equipment
Frame weldments, brackets, and structural components for tractors and implements in harsh outdoor environments.
Hardware & Fasteners
High-volume fasteners, hinges, and stampings requiring uniform thin-film primer at production speed and low cost.
Industrial Fabrications
Welded assemblies and enclosures where weld seams and joints require complete primer penetration for maximum protection.
100% Surface Coverage
E-coat penetrates seams, welds, blind holes, and internal cavities — impossible to achieve with spray painting or powder coating alone.
Zero VOC Waterborne Process
Water-based system with <1% VOC content. No solvent emissions — compliant with the strictest environmental and workplace safety regulations globally.
Self-Limiting Film Build
The deposition process self-limits at target thickness, preventing excess buildup and ensuring batch-to-batch consistency throughout the production run.
High-Volume Production Efficiency
Automated continuous line handles high volumes consistently. 95%+ paint utilisation through ultrafiltration rinse recovery system.
