1. Product Overview
High Durability Polyester Coating (HDP) is a high-performance topcoat for color-coated steel panels. It combineshigh-molecular-weight polyester resin with inorganic ceramic pigments, chemically modified to enhance weather resistance and UV protection. With a service life of 10–15 years, it is widely used in architectural projects requiring long-term resistance to aging and fading.
2. Core Technical Features
·Weather Resistance: Stable molecular structure and high bond energy minimize degradation from sunlight, rain, or temperature fluctuations.
·UV Resistance: Inorganic pigments reduce color fading, outperforming standard polyester coatings.
·Corrosion Resistance: Protects the substrate (e.g., galvanized steel) even if the coating is scratched.
·Coating Process: Two-coat, two-bake roller application ensures uniform thickness and strong adhesion.
3. Application Fields
·Architecture: Industrial plants, warehouses, airports, stadiums, and sloped roofs.
·Other Uses: Vehicle/ship interiors, furniture, and agricultural/livestock buildings.
4. Specifications
·Base Material: Galvalume steel (AZ150) or carbon steel (Q235B).
·Structure: Primer + topcoat (2/1 or 2/2 layers).
·Dimensions: Thickness 0.4–1.2 mm; width up to 1200 mm.
·Warranty: 10–15 years (depends on substrate and coating thickness).
5. Usage Guidelines
·Transport: Secure coils with protective pads to avoid damage.
·Storage: Keep dry and ventilated; avoid outdoor storage.
·Processing: Use protective films during cutting/forming; prioritize timely installation.
