CED Coating Plant in Sri Lanka
SEW Surface Coating Pvt. Ltd. designs, manufactures and installs CED (cathodic electro-deposition) coating plants for manufacturers in Sri Lanka. Every plant is built at our own works in Pune, India, then export-packed and shipped to Sri Lanka, with erection and commissioning support from our engineers.
CED is a water-based primer coating used mostly in automotive paint shops. Charged paint particles move to the component (the cathode) under a direct current, so paint reaches every corner of complex shapes. Un-deposited paint is rinsed and recovered through ultra-filtration (UF), and the film becomes hard after baking.
- Batch & Conveyorised
- UF Paint Recovery
- 1200+ hrs Salt Spray
- Exported to Sri Lanka
CED Coating Plants for Sri Lanka's Industry
Sri Lanka's industry is concentrated around Colombo and the export processing zones at Katunayake, Biyagama, Horana and Koggala. Steel, aluminium, furniture, electrical and engineering makers serve domestic and export markets.
In Sri Lanka, demand for CED coating plants comes mainly from aluminium fabricators, furniture and storage makers and electrical and panel makers. CED primer gives uniform film thickness, full coverage inside box sections and sharp edges, and salt spray resistance of more than 1200 hours. Paint utilisation is close to 100 percent, and because the process is water-based it carries less fire risk than solvent coatings.
Aluminium extruders and fabricators need pretreatment and powder coating for architectural profiles.
Types of CED Coating Plants We Supply in Sri Lanka
Batch Type (Dip Tanks)
Components are loaded in jigs and moved through dip tanks by hoist or PLC-controlled transporter.
Best for: Mixed components and medium volumes.
Continuous Conveyorised
An overhead conveyor carries parts through pretreatment, the CED tank, UF rinses and the baking oven without stopping.
Best for: High-volume automotive and component production.
Combination of Dip and Spray
Spray stages for cleaning and rinsing are combined with dip stages for phosphating and CED, to suit the part and output.
Best for: Lines that need both throughput and full coverage.
CED Coating Process Sequence
The CED process on our plants follows this sequence:
- LoadParts are hung on jigs or the conveyor.
- DegreaseRemoves oil and grease.
- Water Rinse 1 / 2Two rinses after degreasing.
- ActivationPrepares the surface for phosphating.
- PhosphateBuilds the conversion coating.
- DM Water Rinse 1 / 2Clean demineralised water rinses.
- CEDElectro-deposition of primer.
- UF 1 and UF 2Ultra-filtrate rinses recover un-deposited paint.
- DM Water Rinse 3Final rinse before baking.
- Baking OvenThe film is baked hard.
- UnloadParts are inspected and unloaded.
Fully automatic operation needs less manual effort and allows the film thickness to be controlled.
Advantages of CED Over Conventional Primer
Uniform coating
Controlled film thickness and better coverage on interior surfaces, complex shapes and sharp corners.
No runs or sags
No runs, sags or solvent boils, giving a consistent primer surface.
Corrosion resistance
Surface salt spray resistance lasts for more than 1200 hours.
About 100% paint utilisation
UF recovers un-deposited paint, which makes the process cost effective.
Safer and cleaner
Water-based process with less fire risk and fewer pollution and health hazards than solvent coatings.

CED Coating Plant in Sri Lanka – Frequently Asked Questions
Do you export CED coating plants to Sri Lanka?
Yes. SEW Surface Coating Pvt. Ltd. manufactures CED coating plants at its factory in Pune, India, and exports them to customers in Sri Lanka, with erection and commissioning support from our engineers.
What is CED coating?
Cathodic electro-deposition (CED) is a water-based primer coating. Charged paint particles move to the component under direct current, so paint reaches every corner, and the film becomes hard after baking.
What is the role of UF in a CED plant?
Ultra-filtration separates paint ingredients that do not form film and recovers un-deposited paint from the rinses, which gives close to 100 percent paint utilisation.
How much corrosion resistance does CED give?
The baked CED film gives surface salt spray resistance of more than 1200 hours.
Can the CED plant be automatic?
Yes. CED lines run on a PLC-controlled transporter or a continuous conveyor, with automatic operation and controlled film thickness.
How is the plant shipped to Sri Lanka?
The plant is fabricated at our Pune works, export-packed and shipped from Nhava Sheva (JNPT) port near Mumbai to Colombo. Our engineers can travel to supervise erection and commissioning.
