UV Anti-Graffiti Prepainted Aluminum Sheet

Core Advantages

• Premium anti‑graffiti & easy‑clean performance: oil‑based marker, spray‑paint graffiti can be wiped off with rag & neutral cleaner, no special solvent required

• Low‑surface‑energy UV cured topcoat, poor adhesion for ink and adhesive residues, anti‑sticker performance

• High coating hardness, good flexibility, no cracking after normal bending, stable for secondary fabrication

• Superior outdoor UV‑resistance, long‑term anti‑aging, anti‑chalking, anti‑fading for exterior exposure

• Excellent corrosion & salt‑spray resistance, adapt coastal, humid urban environment

• Rich color options: RAL solid colors, metallic, matte / gloss finish; maintain original color texture after repeated cleaning

• Strict pre‑treatment: chromate conversion to guarantee strong coating adhesion, no peeling

• PE protective film covered on surface to avoid scratch during transport & fabrication

Production Process

Aluminum coil uncoiling → Degreasing & cleaning → Chromate conversion pre‑treatment → Primer coating → Base color coating → UV anti‑graffiti top‑coat → UV light curing → Coating performance inspection → Slitting & shearing into sheets → PE film lamination → Dimension & appearance final check → Export packing Each batch tests anti‑graffiti wiping performance, coating adhesion, hardness, salt‑spray and UV‑resistance before shipment。

Stacked neatly onto IPPC fumigated wooden pallets, wrapped with moisture‑proof PE film and stretch film, fixed with packing straps. Shipping marks indicate alloy grade, temper, thickness, dimension, color code, net/gross weight and batch number. MTC, performance test reports and fumigation certificate available for customs clearance and incoming inspection.

FAQ

Q1: How does anti‑graffiti function work? A: UV low‑surface‑energy topcoat reduces ink adhesion. Marker and spray‑paint graffiti can be wiped off with cloth plus mild detergent, will not leave permanent stain.

Q2: Can sheet be bent after UV anti‑graffiti coating? A: Yes, proper temper supports normal bending for panel fabrication; sharp small‑radius bending is not recommended.

Q3: Is it suitable for long‑term outdoor use? A: Yes, UV‑cured topcoat provides excellent anti‑UV aging property for outdoor projects.

Q4: What cleaning material should end‑users adopt? A: Soft cloth with neutral detergent; avoid strong corrosive solvent to protect top‑coat lifespan.

Q5: Available colors? A: Full RAL color range, solid, metallic, matte and gloss finish for custom orders.
