White Color Coated Aluminum for Metal

Selecting a fluorocarbon clear coat requires a comprehensive assessment based on factors such as the intended application environment, performance requirements, and budget constraints. The specific selection logic is outlined below: First, determine the appropriate fluorine content based on the application environment. Fluorine content is the critical metric that determines both weather resistance and cost; therefore, selecting the most cost-effective option for a specific scenario is essential: Standard Outdoor Structures (Suburban municipal buildings, exterior walls/roofs of ordinary residential buildings): Select a standard fluorocarbon clear coat with a fluorine content of ≥70%. This option complies with the outdoor weather-resistance requirements of national standards GB/T 17748 and GB/T 12754, offers a service life of 15–20 years, provides the highest cost-performance ratio, and represents the mainstream choice for most construction projects. Coastal High-Salt-Mist / Heavy-Acid-Rain Industrial Zones: It is imperative to select a high-fluorine, weather-resistant fluorocarbon clear coat with a fluorine content of ≥80%. The higher fluorine content provides superior resistance to salt mist and corrosion, thereby preventing premature aging and fading. Although the initial cost is higher, this choice effectively eliminates the additional expenses associated with future replacement.
