Coil Coating - wide pre-painted aluminium coils
Every year millions of square meters of aluminum coil and aluminum sheets are coated with high-quality paint systems using the coil coating process and supplied worldwide on our wide coil coating plant.
After a wet-chemical pretreatment (cleaning, applying a green chromate coating/chromfree coating), the coils are coated on the back with an adhesive varnish and varnished on the visible side with a topcoat based on polyester, acrylic or PVDF. The polyester coatings belong to the highly weather-resistant systems with simultaneously high ductility and flexibility. Particularly UV-resistant and even more resistant is the PVDF coating, which is coated in 2-3 layers and is particularly popular in facade construction. With acrylic lacquers we can apply up to 60 μm coating thickness in a coil coating pass. Such coatings are particularly suitable in applications where high layer thicknesses are expected. An example are vehicle roofs for bus construction.
