1. General
ALPOLIC®/fr is an aluminum composite material (ACM) with a non-combustible mineral-filled core. Used as an exterior and interior cladding and roof covering on new buildings and retrofit applications, the material is manufactured by Mitsubishi Chemical Functional Products, Inc., and furnished by approved dealers or distributors.
2. Product composition
ALPOLIC ®/fr is composed of a non-combustible mineral-filled core sandwiched between two skins of 0.5mm thick aluminum alloy (3105-H14):
Composition Skin material: 0.5mm thick aluminum (3105-H14)
Core material: Non-combustible mineral filled core
The surface is finished with a high-performance Lumiflon-based fluorocarbon coating, and the back is a wash coating or service coating. ALPOLIC®/fr is available in four finishes: Solid Colors, Metallic Colors, Sparkling Colors and Stone Series. In these finishes, Lumiflon-based fluorocarbon paints are applied in manufacturer's continuous coil coating lines. The Lumiflon-based fluorocarbon coating complies with the "specification for coated coil for exterior building applications" issued by both the ECCA (European Coil Coating Association) and the AAMA (American Architectural Manufacturers Association). Refer to "6. Paint finishes" below for details on ALPOLIC®/fr paint finishes.
The back of ALPOLIC®/fr (which will face the structural wall or steel when it is installed as a cladding panel) has a polyester-based wash coating or service coating to protect it from possible corrosion problems.
The surface is protected with a self-adhesive peel-off protective film consisting of two polyethylene layers of white and black. According to weathering tests under normal outdoor conditions, the protective film will withstand six months' exposure without losing its original peel-off characteristic or causing stains or other damages.

6. Paint finish
(1)Coating system
The surface is finished with Lumiflon-based fluorocarbon coating; the back is a wash coating or service coating. ALPOLIC®/fr is available in four finishes: Solid Colors, Metallic Colors, Sparkling Colors and Stone Series. In these finishes, Lumiflon-based fluorocarbon paints are applied in the manufacturer's coil coating lines. The coating system for each finish is:
A. "Solid Colors" are a two-coat two-bake system.
The total dry film thickness is 25 minimum and consists of a conversion coating, an inhibitive primer and a Lumiflon-based fluorocarbon coating.
B. "Metallic Colors" and "Sparkling Colors" are three-coat three-bake system.
The thickness is 35 minimum and consists of a conversion coating, an inhibitive primer, a Lumiflon-based metallic coating and a clear coating.
C. "Stone Series" is coated with a unique image transfer process.
The thickness is 45 minimum and consists of a conversion coating, an inhibitive primer and a Lumiflon-based fluorocarbon coating including the image transfer layer.
