Key Selling Points

• 1,000+ Hour Salt Spray Resistance: Molecular-level bond isolates metal from moisture and road salts, proven by over 1,000 hours NSS testing.
• 360° Uniform Coverage: Faraday's principle ensures >95% coverage even in deep cavities and internal holes, eliminating corrosion dead corners.
• ±1µm Thickness Precision: Automated lines control coating thickness to within ±1µm tolerance for consistent anti-corrosion performance.
• Eco-Friendly Water-Based: Zero heavy metals, ultra-low VOC, compliant with RoHS and international environmental standards.
• Proven Adhesion & Durability: Withstands stone chipping, temperature extremes (-40°C to +85°C), and assembly torque without peeling.

Technical Specifications

Models and Options

Standard black E-coating is available in matte or glossy finish. Thickness and color can be customized per customer requirements. We also offer variants for different substrates: zinc alloy, aluminum alloy, magnesium alloy, and stamping parts.

Materials and Structure

The coating is based on acrylic/epoxy resin (water-based). It forms a dense cross-linked structure that bonds molecularly with the metal substrate, providing excellent adhesion and abrasion resistance.

Applications

Common applications include automotive fasteners, chassis components, body frames, door hinges, engine brackets, electric motor housings, bicycle accessories, cooling fans, die-cast parts, CNC machined parts, and metal stamping parts.

Customization

• Coating thickness: Customizable within 15-25µm range
• Color: Black, grey, silver, or custom colors
• Gloss level: Matte or glossy
• Packaging: According to customer specifications

Case Study

Motor Housing for Japanese Motor Manufacturer

Quantity: 15,000,000 units
Application: Anti-corrosion E-coating for electric motor housings
Result: Achieved over 720 hours neutral salt spray resistance, extending product lifespan by 5-10 years compared to non-E-coated parts. Uniform full coverage of complex motor structural gaps ensured stable performance under harsh conditions.
