PVDF (Polyvinylidene Fluoride) is a high-performance coating used on ACP panels for exterior applications. Made with 70% KYNAR 500 resin, PVDF coating provides 25+ year colour retention, superior UV resistance, chemical resistance, and self-cleaning properties. VIVA uses PVDF coating on all exterior-grade ACP panels manufactured on Korean precision lamination lines.
PVDF (Polyvinylidene Fluoride) is a fluoropolymer coating that forms an extremely durable, weather-resistant finish on aluminium composite panels. The key ingredient is KYNAR 500 resin — a registered trademark of Arkema. VIVA uses 70% KYNAR 500 content, which is the highest grade available globally.
PVDF: 25+ year colour retention, UV resistant, chemical resistant, self-cleaning, anti-chalking. Cost: 30-40% more than PE. Use: All exterior applications.
PE (Polyester): 5-7 year colour retention, fades in sunlight, not chemical resistant. Cost: Lower. Use: Interior only.
VIVA's PVDF coating meets AAMA 2605 (American Architectural Manufacturers Association) specification — the highest performance standard for architectural coatings. This ensures: minimum 10 years colour change ΔE ≤5, minimum 10 years chalk rating ≤8, and minimum 10 years gloss retention ≥50%.
The percentage refers to the KYNAR resin content in the PVDF paint formulation. Higher KYNAR content = better performance. 70% is the industry gold standard. Some manufacturers use 50% KYNAR to reduce cost — resulting in inferior weather resistance. VIVA guarantees 70% KYNAR 500 on every PVDF panel.
An Aluminium Composite Panel (ACP) is a flat panel consisting of two thin coil-coated aluminium sheets bonded to a non-aluminium core material, typically polyethylene (PE), mineral-filled fire-retardant (FR), or aluminium honeycomb. ACP panels are used for building facades, signage, interiors, and architectural cladding due to their lightweight, weather resistance, and design versatility.
Read full answer →ACP stands for Aluminium Composite Panel. It is also referred to as ACM (Aluminium Composite Material) or ACCP (Aluminium Composite Core Panel) for fire-rated variants. VIVA manufactures standard ACP, FR B1 fire-rated ACP, and FR A2+ ACCP with aluminium corrugated core.
Read full answer →For exterior cladding, PVDF-coated ACP with 70% KYNAR 500 resin is the best choice. VIVA recommends 4mm PVDF panels for standard exteriors and 4mm/6mm FR A2+ ACCP for buildings above 15 meters. The Solid & Metallic, Natural Stone, Premium Marble, and Mirage Fluted series are the most popular for exterior facades.
Read full answer →Yes, ACP sheets are waterproof. The aluminium skins and PVDF/PE coating create a moisture-impervious surface that does not absorb water, swell, or degrade with water exposure. ACP panels are ideal for exterior facades, monsoon-prone regions, and humid environments. However, proper sealing of panel joints with weather-grade silicone sealant is essential for a watertight facade system.
Read full answer →VIVA ACP sheets are available in standard sizes of 1220mm × 2440mm (4×8 ft), 1220mm × 3050mm (4×10 ft), and 1220mm × 3660mm (4×12 ft). Wide panels of 1500mm width are also available. Custom lengths up to 6000mm can be manufactured on request for large-scale projects.
