Coating Benefits
Why Epoxy Powder Coating
Our dip-coating process upgrades copper busbars on six fronts — lowering cost while extending service life.
Corrosion Resistance
A dense epoxy layer seals copper from moisture, salt spray and oxidation for lasting reliability.
Wear Resistance
The cured coating resists abrasion and mechanical wear during assembly and daily operation.
Electrical Insulation
High dielectric strength prevents short circuits and allows tighter, safer busbar layouts.
Aesthetic Finish
A smooth, even, colour-customisable surface gives every part a premium, professional look.
Lower Cost & Maintenance
Longer-lasting parts cut replacement and maintenance spend across the product lifecycle.
Longer Service Life
Combined protection significantly extends the working life of connectors in harsh environments.
Process
Our Coating Process
Four controlled stages ensure a consistent, high-quality finish on every batch.
01
Surface Pre-Treatment
Degreasing, cleaning and activation prepare the copper for maximum coating adhesion.
02
Powder Dipping
Pre-heated parts are dip-coated in epoxy resin powder for a uniform, fully-enclosing layer.
03
High-Temp Curing
Parts are cured in temperature-controlled ovens so the coating bonds hard and even.
04
Inspection & Delivery
Thickness, insulation and appearance are checked before careful packing and shipment.

FAQ
Frequently Asked Questions
What buyers most often ask about our copper busbar coating service.
Are you a factory or a trading company?
We are a direct manufacturer — Guangzhou Doolike — with a 3000㎡ workshop, 50+ technicians and our own powder-dipping, plastic-dip and coating lines. You buy at source-factory prices with full technical support.
What is the difference between powder coating, plastic dip coating and spray coating for busbars?
Epoxy powder dip coating gives a hard, insulating, corrosion-resistant film; plastic (PVC/plastisol) dip coating gives a thicker, softer insulating layer; electrostatic spray coating suits flat, decorative finishes. We recommend the best process for your busbar and application.
Do you accept custom orders (OEM/ODM)? Is there a minimum order?
Yes. We coat copper busbars and connectors to your drawings — any shape, size or colour — with fast sampling and flexible order quantities. Send us your specifications for a tailored quote.
What performance does the coating achieve?
Better corrosion resistance, wear resistance, high dielectric insulation and a clean, colour-customisable finish — lowering maintenance cost and extending service life for EV, battery, solar and energy-storage busbars.
What is your lead time and do you export?
Sampling is fast; bulk lead time depends on quantity and finish. We serve customers across China and worldwide and support export shipping.
How do I get a quote?
Send your busbar drawings or specifications (material, size, coating type, colour, quantity) by email, WhatsApp or WeChat and we reply with a tailored quote within 24 hours.
