The Ultra-Weather-Resistant Powder Coatings series can provide customers with 10-20 year weather resistance warranties, fluorocarbon powder coatings, high-strength UV-resistant powder coatings, anti-yellowing powder coatings, and zinc-rich powder coatings, all tailored to customer requirements. All products use imported raw materials, each carefully selected and subjected to rigorous weather resistance testing. The final formulations meet or exceed international standards, such as those of the European Aluminium Association (Qualicoat) and the American Architectural Manufacturers Association (AAMA). This series includes two main categories: ultra-weather-resistant polyester and fluorocarbon powder coatings.
The Ultra-weather-resistant powder coatings series is suitable for a variety of substrates, especially architectural profiles, offering excellent weather resistance and good resistance to damage from packaging materials. The products come in a wide range of colors and are available in gloss, semi-gloss, and matte finishes; sand texture, aluminum powder, pearlescent, and other special effects are also available. They are widely used in applications requiring high weather resistance, such as sprayed aluminum alloy profiles, aluminum curtain wall panels, aluminum ceiling panels, aluminum doors and windows, railway components, highway guardrails, and aluminum ceilings.

The ultra-weather-resistant powder coatings series can be applied using manual or automatic spraying equipment, ensuring the use of a clean air source.
Atomizing air pressure: ~0.7 bar
Primary air pressure: ~0.7 bar
Recommended voltage: 40~90 kV
During spraying, ensure that ventilation and dust collection systems are functioning properly, and that personnel take appropriate protective measures and wear suitable protective equipment. For more detailed information, please refer to the safety data sheet for the corresponding product.
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.
