Alucobond^® Thin Metal Composite Sheets (TMCS) from 3A COMPOSITES GmbH company consist of two thin layers of aluminium skin, which are sandwiching a core in a continuous coextrusion process. The external aluminium skin is always pre-treated or pre-coated and the bonding of the metal skins to the core is achieved by an adhesive applied to both faces of the core, bonded by temperature and pressure under controlled conditions.

The TMCS are composed by:

• Faced skins made of aluminium alloy according to EN 485-2 or EN 573-3, surface treated (coil coated according to EN 1396) or not, of 0,50 mm each.
• Solid core made of polymer with ≥ 90 % mineral filler with polymeric binder (Alucobond^® A2) or ≥ 70% mineral content (Alucobond^® Plus).
• Adhesive layer of bonding faced skins and core through a continuous industrial process.

The panel has a total thickness of 4 mm and a surface weight of 8 kg/m² and is cut to a range of panel sizes going from 2000 mm to 8000 mm, and on widths of 1000 mm, 1250 mm, 1500 mm and 2000 mm, enabling vertical or horizontal modulation of the cladding.

Alucobond^® A2 and Alucobond^® Plus TMCS are used as:

• Cladding elements (cassettes/coffering, panels) in external and internal wall cladding kits.
• Parts (filling elements) of partition kits.
• Filling elements in external or internal supported ceilings.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The assessment in ETA 22/0477 has been done according to EAD 210046-00-1201 Thin metal composite sheet. Mechanical and durability characteristics related to the use of the panels as external wall cladding elements have been assessed, as well as the reaction to fire of the panels.
