What is the difference between ACP and ACM?

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.

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.

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.

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.

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.
