Properties
ArcelorMittal backing coats offer a full range of specific properties: foam adherence, mechanical properties and corrosion resistance.
Backing coats may be applied in one or two layers, with a total thickness between 5 and 12 µm.
Advantages
Backing coats protect the back of organic coated sheet steel. They are compulsory and prevent any friction between windings. Several levels of corrosion resistance and mechanical strength are available. The backing coats are designed to ensure good foam adherence, but users are advised to check this property with their own specific foam products.
