Electrophoresis Aluminum Profiles
Bright and Aesthetic Finish: Electrophoretic coating delivers a highly transparent, smooth surface with enhanced metallic luster and a refined decorative effect.
Excellent Corrosion Resistance: It forms a dense protective layer, effectively resisting acids, alkalis, and salts, suitable for various environments.
High Hardness and Wear Resistance: The coated surface reaches a hardness of up to 4H, providing good durability against abrasion.
Electrical Insulation: The coating acts as an insulating layer, improving the profile’s safety in relevant applications.
Electrophoresis Coating
The electrophoretic coating layer applied to aluminum profiles is primarily composed of water-based resins, pigments, additives, and crosslinking agents. This formulation results in a smooth, uniform, and visually appealing film with excellent adhesion properties. One of the key advantages of the electrophoretic process is its ability to produce an even coating, not only on flat surfaces but also over edges, weld seams, grooves, and other irregular or intricate areas of the profile. As a result, the entire aluminum profile receives comprehensive protection and a consistent decorative finish.
Aluminum Electrophoretic Process
Electrophoretic Coating Line
The electrophoretic coating production line typically shares much of its equipment with the anodizing line, utilizing the same pre-treatment and preparatory processes. Before entering the electrophoresis stage, aluminum profiles undergo anodizing treatment, which is essential for improving the adhesion of the subsequent coating layer. This combined approach ensures a uniform, durable, and aesthetically pleasing finish on the final product.
Electrophoretic Coating Film Thickness
The final film thickness on electrophoretically coated aluminum profiles includes both the anodized oxide layer and the electrophoretic coating layer, offering enhanced protection and durability.
| Grade | Anodized film thickness | Electrophoretic film thickness | Total film thickness |
|---|---|---|---|
| A | 9um | 12um | 21um |
| B | 9um | 7um | 16um |
| S | 6um | 21um | 15um |
Electrophoretic Coating Color
The electrophoretic layer on aluminum profiles offers a range of color options to meet different aesthetic and design requirements. Common colors include clear, champagne, bronze, black, and gold, among others. The color is determined by the selection of pigments and the specific formulation of the coating, allowing for both vibrant and subtle finishes.
Features of Electrophoretic Coating
Excellent Insulation: The coating is primarily composed of resin materials, which inherently provide electrical insulation. Moreover, the uniformity and coverage of the layer further ensure reliable insulating properties across the entire surface.
High Hardness: The electrophoretic film exhibits impressive surface hardness, reaching up to 4H. This characteristic significantly improves the profile’s resistance to scratches and wear.
Easy to Clean: The smooth and non-porous surface of the electrophoretic coating makes it resistant to stains and easy to maintain, supporting long-lasting aesthetic appeal.
Fingerprint Resistance: The electrophoretic coating provides an exceptionally smooth and non-porous surface, which significantly reduces the appearance of fingerprints and smudges.

Aluminum Electrophoretic VS Anodized
| Item | Anodized Aluminum Profiles | Electrophoretic Aluminum Profiles |
|---|---|---|
| Process | Anodic oxidation forms oxide layer | Anodized surface plus electrophoretic coating (organic film) |
| Appearance | Matte or satin metallic gloss | Bright, glossy, smooth, mirror-like effect |
| Color Options | Limited, lighter colors preferred | Wider color range, deep and uniform colors |
| Corrosion Resistance | Good, but oxide layer can be damaged | Excellent, dual protection (oxide + coat), ideal for harsh environments |
| Wear/Scratch Resistance | Basic, susceptible to scratches | Excellent, firmly bonded double-layer, more scratch-resistant |
| Surface Texture | Slight grain, less smooth | Very smooth, fine touch |
| Cleanability | Easier to get fingerprints or stains | Easy to clean, anti-fingerprint, anti-pollution |
| Environmental Performance | Good, no heavy metals | Better, generally water-based, more eco-friendly |
| Typical Applications | Standard frames, doors/windows, heat sinks, cost-sensitive projects | High-end doors/windows, curtain walls, decorative profiles, bathroom furniture |
Electrophoretic Aluminum Section Applications
Architectural Doors, Windows, and Curtain Walls:
Electrophoretic aluminum profiles are widely used in high-end residential and commercial buildings for doors, window frames, curtain wall structures, and decorative trims. They are especially popular for entrance doors, sunrooms, and other applications that require both a premium appearance and excellent corrosion resistance.
Decorative Aluminum Components:
These profiles serve as interior and exterior trims such as skirting boards, door or window casings, and ceiling trims. They are often found in both home décor and public spaces, where both decoration and durability are important.
Bathroom and Sanitary Ware:
Electrophoretic aluminum profiles are ideal for use in bathrooms due to their moisture resistance. Common applications include frames for bathroom cabinets, mirror cabinets, towel racks, as well as shower room profiles and sliding door tracks.
Furniture and Home Products:
They are used in cabinet doors, wardrobe frames, sliding door aluminum profiles, TV background walls, screens, display cases, and decorative strips. In addition, these profiles are found in office partitions and various furniture aluminum components.
Transportation and Rail Transit:
In the field of transportation, electrophoretic aluminum profiles are chosen for their durability and appearance in high-speed rail, subways, and airport facilities. Typical uses include train doors and windows, luggage racks, and handrails.
Industrial Equipment Housings:
These profiles are applied in machinery enclosures, equipment cabinets, workshop safety barriers, and medical device casings. Their attractive appearance and robust protection also make them suitable for automatic doors and display equipment.
Other Applications:
Electrophoretic aluminum profiles are also commonly used in lighting fixtures, electronic product frames, aluminum photo frames, art frames, and other products that require both a high level of aesthetics and protection.
