Fluorinated Polyester Powder Coating is a high-performance exterior-grade powder coating formulated with fluorinated polyester resin technology. You use this system when you need improved weather resistance, long-term color stability, and better gloss retention compared to conventional polyester coatings.
It is designed for architectural and industrial metal components exposed to outdoor environments. The fluorinated modification enhances UV durability while maintaining good mechanical properties and application stability. This coating system can be evaluated according to international standards such as ISO 9227 for corrosion resistance and ASTM G154 for accelerated weathering performance.
Fluorinated polyester technology offers a practical balance between performance and cost for exterior projects requiring extended service life.

Performance results depend on pretreatment quality and total coating system design.
Enhanced UV Resistance
You achieve better long-term gloss and color retention compared to standard polyester powder coatings, especially in high UV regions.
Improved Weather Durability
The fluorinated structure improves resistance to sunlight, moisture, and environmental aging.
Stable Mechanical Performance
You maintain strong adhesion, flexibility, and impact resistance suitable for fabricated metal components.
Wide Gloss and Color Range
You can select from matte to high-gloss finishes, making it suitable for modern architectural designs.
Environmental Compliance
As a solvent-free powder coating, it generates no VOC emissions during application and supports environmentally responsible production.
For reliable long-term performance, you should ensure proper pretreatment:
Aluminum: chromate-free or equivalent conversion coating
Steel: degreasing, phosphating or equivalent pretreatment
Clean, dry substrate prior to coating
Proper surface preparation is critical for corrosion resistance and coating adhesion.
Aluminum Curtain Wall Project – Subtropical Climate
You required a durable exterior coating system for aluminum façade panels exposed to high humidity and strong sunlight. Fluorinated Polyester Powder Coating was selected to improve weathering resistance compared to conventional polyester.
After accelerated weathering evaluation according to ASTM G154 and corrosion testing following ISO 9227, the coating system maintained stable gloss and showed no adhesion loss. The project achieved improved long-term appearance retention under outdoor exposure.
Apply by electrostatic spray equipment
Maintain consistent film thickness within recommended range
Control curing temperature based on actual metal temperature, not oven air temperature
Perform small-batch trials before full production
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.
