The Surpass MT-A600 Series powder coating is a high-performance coating designed specifically for computer cases, including desktop and notebook enclosures. 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.
Peripheral Equipment: Used for monitors, printers, and server cabinets requiring a professional, durable finish.
