| High Light | 3105 aluminum coil refrigerator back panel ，PVDF prepainted aluminum coil ，fingerprint resistant aluminum alloy coil | ||
The 0.4–0.8 mm 3105 PVDF coated aluminum coil is currently the premium upgrade choice worldwide for refrigerator back panels (also called rear covers, condenser guards, structural back sheets or rear liners) — especially in high-end, coastal-market and fingerprint-conscious models.
Compared to 1060/1100 (softer & lower strength) or 5052 (stronger but 20–40% more expensive), 3105 delivers the optimal balance for modern refrigerator manufacturing:
Mn alloying (1.0–1.5%) → 20–30% higher yield strength than 1060 → better dent resistance from transport & installation
Very good thermal conductivity (~170–180 W/m·K) → efficient condenser heat dissipation
Superior PVDF coating adhesion & fingerprint-resistant performance
Cost-effective yet premium appearance & durability for visible / semi-visible back panels
Coating system:PVDF fluorocarbon (Kynar 500® equivalent): 25–35 μm, 3-layer structure,Fingerprint-resistant nano topcoat (oleophobic),Standard colors: RAL 9003 signal white, RAL 7035 light gray, metallic silver,Warranty: 25–30 years indoor color stability, gloss retention & scratch/fingerprint resistance

Q1: Why choose 3105 over 1060 or 5052 for refrigerator back panels?
A: 3105 offers ~20% higher strength than 1060 (better dent resistance during transport & installation) while being 15–25% lower cost than 5052. It is the sweet spot for premium & coastal-market refrigerators where fingerprint resistance & long-term appearance matter.
Q2: How effective is the fingerprint-resistant coating & is it durable?
A: Nano oleophobic topcoat hardness 2H–3H; fingerprints & grease wipe off with dry cloth in seconds. Abrasion & touch-test reports (ASTM D4060) show durability after thousands of cycles.
Q3: What is the thermal conductivity & how does it affect refrigerator efficiency?
A: ~170–180 W/m·K — 15–25% better heat dissipation than painted steel back panels. Many OEMs report 2–5% improvement in overall energy efficiency.
Q4: Minimum order quantity & lead time for custom colors?
A: MOQ 3–5 tons (depending on color); standard white/gray 15–25 days; custom RAL match 25–35 days. Sample coils free with freight collect.
Q5: How does 3105 PVDF perform in high-humidity / coastal markets?
A: Excellent — PVDF coating passes 3000–5000 h salt-spray; no white rust or pitting in 90%+ humidity kitchens. Humidity chamber & coastal exposure data available.
Q6: Is 3105 suitable for visible back panels in premium models?
A: Yes — fingerprint-resistant PVDF provides premium appearance & easy cleaning. Widely used in fingerprint-conscious high-end refrigerators.
