It combines excellent aesthetic appeal with superior physical and chemical properties, ensuring durability and reliability in demanding environments.
Coating Characteristics
High-Gloss/Matte Finish: Offers a smooth, uniform, and high-quality appearance, available in various textures (e.g., metallic, brushed).
Excellent Adhesion: Achieves 0-level adhesion (GB/T 9286), ensuring long-term durability and resistance to peeling.
Wear and Impact Resistance: Withstands 50 kg·cm impact (GB/T 1732) and 500 cycles of Taber abrasion (CS-10 wheel, 1 kg load) without visible damage.
Chemical Resistance: Resists 99% IPA (isopropyl alcohol) for 24 hours, household cleaners, and oils without surface degradation.
Anti-Pollution Performance: Effectively repels fingerprints, dust, and stains, maintaining a pristine appearance.
Applications
Desktop Computer Chassis: Ideal for gaming PC cases, workstation enclosures, and custom-built systems.
Notebook Computer Enclosures: Suitable for premium laptop shells, 2-in-1 convertibles, and ruggedized devices.
