Aluminium Panel Composite

1. aluminium panel composite Coating & Durability Performance

·Coating structure: Multi‑layer fluorocarbon coating system with nano topcoat finish

·Number of layers: 4 layers (primer + PVDF base coat + intermediate coat + nano topcoat)

·Description of nano topcoat technology: Nano‑modified particles integrate into top surface, boost self‑cleaning, anti‑pollution and scratch resistance for long‑term outdoor use.

·Total coating thickness (microns): 25‑35μm total

·PVDF base layer: 18‑24μm

·Nano topcoat layer: 6‑11μm

·Type of resin used: Kynar 500® PVDF fluorocarbon resin

·Coating Supplier: Well‑known domestic fluorocarbon coating manufacturer

Performance Data (with test standards)

·UV resistance (expected lifetime in years): 20‑25 years outdoor, test standard: ASTM G154

·Color retention (ΔE values): ΔE ≤3 after 2000h UV accelerated test, ASTM G154

·Gloss retention (%): ≥80% gloss retention after 2000h UV test

·Chalk resistance: Chalk degree ≤1, ASTM D4214

·Salt spray resistance (hours): ≥2000 hours, ASTM B117

·Chemical resistance:

 ‑Acid / Alkali resistance: Resist dilute acid and alkali corrosion, ASTM D1308

 ‑Pollution resistance / self‑cleaning performance: Nano topcoat delivers good anti‑stain & self‑cleaning effect, dirt washes away by rainwater

 ‑Abrasion resistance: ≥700g wear resistance, ASTM D4060

 ‑T‑bend / flexibility: 0T bend without coating crack, ASTM D4145
