UV resistant oxidation&dual color anodizing solution Precise craftsmanship, long-term protection, and aesthetic innovation

Dongguan Tongtoo Aluminum Products Co., Ltd. has been deeply involved in the precision machining and anodizing of aluminum alloys for 20 years, focusing on providing customized surface treatment solutions for industries

such as aerospace, new energy vehicles, consumer electronics, and high-end construction.

UV resistant anodizing

UV protection expert, guarding the natural color of metals For aluminum alloy components in outdoor and strong light environments, we adopt patented UV resistant anodizing technology. By optimizing the electrolyte formula and sealing process, we form a high-density oxide film

layer, effectively blocking UV erosion and extending the product's service life.

Core advantages Super weather resistance The UV absorption rate of the oxide film layer is ≥ 95%. After 1000 hours of QUV aging test, the color difference AE is ≤ 1.5, and the anti powdering level reaches ASTM level 1. The color is durable and stable Nano level sealing technology locks dye molecules, allowing for 3 years of outdoor exposure without significant fading, maintaining a metallic texture and color saturation.

Environmental protection and energy saving The entire process complies with ROHS/REACH standards

Typical applications

Outdoor building curtain wall/solar bracket Automotive exterior parts/drone body Sports equipment/outdoor signage

Dual color anodizing process One device with two colors, defining a new dimension of metal aesthetics By using precision masking, gradient oxidation, or secondary anodizing techniques, dual color/gradient effects can be achieved on the same aluminum alloy workpiece, breaking through the limitations of traditional single

color and injecting differentiated design language into the product. Process highlights

Precise boundary control The laser mask has an accuracy of ± 0.1mm, with clear and sharp transitions of color blocks, and supports customization of complex patterns.

Free color combination We offer over 100 color card options, which can be paired with matte/glossy, same color scheme/contrasting effects.

Non destructive superposition of performance The dual color area has passed a 48 hour salt spray test to ensure functionality is not affected by visual design.

Innovative application scenarios

Consumer electronics: Notebook computer A-side L0go dual color inlay Industrial Design: Visual Guidelines for Functional Zoning of Instruments and Meters High end retail: luxury display cabinets with metal decorations

frequently asked questions Q: Does dual color oxidation affect the conductivity of components? A: The anodic oxide film itself is insulating, but the conductivity of the designated area can be retained through local stripping process.

Q: Can UV resistant treatment be combined with hard oxidation? A: Supports composite technology, with a surface hardness of up to HV600 and UV resistance
