When selecting aluminum-plastic panels, many people focus solely on decorative effects, thickness, and price, overlooking the "hidden strength" of coatings—the weather resistance, service life, and suitability for different scenarios vary drastically among different types.
Today, we will delve into the core differences of mainstream surface coatings for aluminum-plastic panels, ensuring your panels remain stable and durable for over a decade.
Fluorocarbon coating: the "unyielding champion" for outdoor scenarios
As the core coating of high-end aluminum-plastic panels, fluorocarbon coating (PVDF/EVE system) has become the preferred choice for long-term outdoor use scenarios due to its excellent performance, and is known as the "weather resistance champion" in the coating industry.
Core advantages:
Strong weather resistance: The carbon fluorine bonds in the molecular structure of fluorocarbon coatings are very stable, and only a small proportion of photons in ultraviolet light can break the C-F bonds, so they can effectively resist UV aging. They do not fade or pulverize after long-term exposure to sunlight, and can also resist acid and alkali corrosion, salt spray erosion, and are suitable for harsh environments such as coastal areas, high temperatures, and high humidity;
Wide temperature adaptability: Fluorocarbon coatings can withstand extreme temperature differences of -50 ℃ to 70 ℃, and can maintain stable performance in cold and hot regions without cracking, deformation, or discoloration;
Long service life: The outdoor standard service life of fluorocarbon coating can reach 15-20 years, which is 2-3 times that of ordinary coating, and the maintenance cost is extremely low;
Adaptation scenario:Outdoor curtain wall decoration for large public buildings such as advertising signs, outdoor decoration projects, and office buildings/exhibition centers is particularly suitable for high-end projects that require high durability and aesthetics.
Polyester coating: the "cost-effectiveness benchmark" for indoor scenes
Polyester coating is currently the most widely used type of coating, which meets the requirements of appearance, performance, and cost. It is perfectly suitable for indoor decoration and short-term outdoor scenes, with a high cost performance ratio.
Core advantages:
Performance standards: The core indicators of polyester coating adhesion, flexibility, and scrub resistance fully comply with national standards and can meet the daily decorative needs;
Rich appearance: With a variety of color options, it can achieve various textures such as matte, high gloss, and metallic colors. The pattern expression is strong and can match different decoration styles;
Cost friendly: The price is 30% -50% lower than fluorocarbon coatings, and the service life can reach 8-10 years in indoor environments without the need for high-frequency replacement.
Adaptation scenario:Indoor ceiling, column decoration, display cabinet panels, indoor curtain walls, commercial space interior wall decoration, etc.
