ALPOLIC/fr ZCM is a zinc composite material composed of chemically-weathered zince sheet on the topside, a non-combustible mineral-filled core and a zinc sheet on the backside. ALPOLIC/fr ZCM is suitable for the external applications such as soffits, awnings, parapets, rain screens, external cladding and roofs, especially when conventional building materials are sufficient.
Zinc alloy skin: The topside skin is a real zinc alloy weathered with a chemical conversion process, which later takes on a distinctive grat appearance through natural weathering.
Long life: Protected by the surface layers, zinc allow has a long life. The annual erosion rate is normally 1 to 7 microns (3 microns on average), which indicates that 100 microns (0,1mm) thick zinc takes as long as 35 years to erode.
2. Product Composition
ALPOLIC/fr ZCM is composed of a non-combustible mineral-filled core sandwiched between two skins of 0.5mm thick zinc:
