Computer Case Powder Coatings are specifically formulated for desktop computer cases, laptop casings, and similar electronic housings. You benefit from a coating that delivers an excellent appearance, strong adhesion, high wear and impact resistance, and robust chemical resistance to solvents, alcohols, and everyday contaminants. This ensures that your computer enclosures remain visually appealing, durable, and protected under frequent handling and use.
You can apply these powder coatings on:
Desktop computer chassis
Laptop outer casings and frames
Server cabinets and electronic housings
External peripherals such as keyboard panels or docking stations
Test Substrate: Performance tests are conducted on 0.8 mm degreased and derusted steel or aluminum panels to simulate computer case surfaces.

You achieve superior coating appearance with smooth or metallic finishes suitable for consumer electronics
You benefit from high adhesion, ensuring the coating remains intact under mechanical stress
You gain excellent wear and impact resistance, protecting your device from scratches and dents
You maintain chemical resistance against alcohols, solvents, and cleaning agents
You enjoy long-lasting performance with stable color and gloss retention even under frequent handling
We helped a gaming desktop manufacturer improve durability and aesthetics of their cases. By applying our Computer Case Powder Coatings, you reduced visible wear from repeated handling, improved scratch and impact resistance, and ensured the coating maintained color stability even after repeated cleaning with alcohol-based wipes. End-users reported improved visual appeal and longevity, while production maintained consistent film thickness and surface finish across all batches.
Powder coatings can be categorized by resin system (epoxy, polyester, hybrid, polyurethane), appearance (smooth, texture, hammer, metallic, pearlescent), or performance level (anti-corrosion, heat-resistant, UV-resistant, architectural grade, automotive grade).
Powder coatings offer thousands of colors in gloss, matte, satin, metallic, candy, texture, wrinkle, hammer tone, wood grain, fluorescent, and other custom effects. Special powders can create soft-touch, anti-scratch, anti-fingerprint, or anti-graffiti surfaces.
The process generally includes surface pretreatment (degreasing, phosphating, chromating, sandblasting), drying, electrostatic spraying, curing in an oven, and cooling. A well-controlled pretreatment and curing process ensures strong adhesion and long service life.
Powder coatings are environmentally friendly, solvent-free, and produce minimal waste. They offer excellent corrosion resistance, weather durability, mechanical strength, and uniform film appearance. The coating is tough, impact-resistant, scratch-resistant, and has a long lifespan.
Powder coatings are widely used in appliances, aluminum profiles, architectural components, automotive parts, bicycles, furniture, outdoor equipment, machinery, electrical cabinets, pipeline systems, and general industrial and consumer goods.
Powder coating is a dry finishing technology where finely ground powder is electrostatically sprayed onto a metal or non-metal surface and then cured at high temperature. After curing, the powder melts into a continuous, durable, and decorative coating layer.
Powder coating protects the substrate from corrosion, weathering, chemical attack, and mechanical wear. It also provides decorative appearance with rich colors, gloss levels, textures, and special effects.
In many industrial applications, powder coating outperforms liquid paint. It forms a thicker and tougher coating, resists corrosion and chemicals better, and does not contain VOCs. It also provides excellent consistency and cost-effective mass production.
It is called powder coating because the coating material is a solid powder instead of a liquid paint. The coating is formed by melting and curing powder particles under heat.
Powder coatings include several families depending on resin chemistry:
• Epoxy powders
• Polyester powders
• Epoxy-polyester hybrid powders
• Polyurethane powders
• Acrylic powders
• Fluorocarbon (PVDF) powders
Each type has its own performance features such as corrosion resistance, UV resistance, chemical resistance, outdoor durability, or decorative properties.
Powder coatings are based on thermoset or thermoplastic resins combined with pigments, curing agents, fillers, additives, and in some cases metallic or effect particles. Common substrates include steel, aluminum, galvanized metal, MDF, and certain heat-resistant plastics.
The lifespan depends on powder type, film thickness, application method, pretreatment, and service environment. Indoor coatings can last more than 10–20 years. High-grade outdoor polyester or fluorocarbon powders can last 15–25 years or longer under UV exposure.
