Thermosetting decorative powder coating is a new generation of metal surface treatment technology. It forms wear-resistant, corrosion-resistant, and highly decorative coatings through electrostatic spraying and high-temperature curing. It is widely used in home appliances, building materials, automotive parts, and outdoor facilities. With zero VOC emissions, it meets RoHS/REACH environmental certifications and is a green alternative to traditional paints.
Adhesion: 0 grade (cross-cut method) (ASTM D3359)
Salt spray resistance: No bubbling after 1000 hours (ASTM B117)
Pencil hardness: ≥ 2H (ASTM D3363)
Gloss: Adjustable from 10 to 95 GU (ISO 2813)
Vibrant Colors and Endless Creativity: Offers a wide range of colors, from classic solids to brilliant metallic finishes, unique fluorescent and transparent effects, meeting all color fantasies and adding unique charm to the work.
Strong Thermosetting and Durability: Advanced thermosetting technology ensures the coating is tough after heating, with excellent wear and corrosion resistance. It maintains color vibrancy even in harsh conditions.
Environmentally Friendly and Safe: No solvents, low VOC emissions, meets national environmental standards, no odors during application, ensuring the health of workers and users, creating a green living space.
Easy to Apply and Efficient: Powder coatings can be applied via electrostatic spraying or fluidized bed dipping. The process is simple, with fast drying, high efficiency, reduced project time, and lower costs.
Artistic Texture and Enhanced Value: Unique decorative effects, such as textures, metallic finishes, and contrast between matte and glossy, significantly enhance visual appeal and product value, making your work stand out among competitors.
Home Appliance Industry
Refrigerator/oven/air conditioner casings: Anti-fingerprint matte coatings for aesthetics and easy cleaning.
Washing machine inner cylinders: Corrosion-resistant coatings to extend lifespan.
Automotive Parts
Wheels/chassis: Metallic glossy coatings for visual upgrade.
Engine hoods: High-temperature textured coatings (-50°C to 200°C stability).
Construction and Outdoor Facilities
Aluminum curtain walls/balustrades: UV-resistant fluorocarbon powders for 20-year outdoor color retention.
Streetlights/traffic signs: Reflective coatings for enhanced night-time visibility.
Creative Design Field
Furniture/art: Wood grain or stone grain coatings to achieve natural material textures at low cost.
Electronics: Gradient coatings for differentiated appearance.
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.
