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.
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.
Below is a description of the backing coat range, together with a few examples of possible applications.
|Coating type||Thickness||Main properties||Examples of applications|
|Backing coat||5 µm||Compatible with foams||Sandwich panels|
|7 µm||Compatible with foams and homogeneous surface appearance (no colour guarantee)||Recommended for indoor applications|
|10 µm||Compatible with foams and colour homogeneity||Recommended for outdoor applications|
|12 µm monolayer or bi-layer||Compatible with foams, robust backing coat||Recommended with Granite® HDX and Granite® Storm and compulsory with Granite® HDX, Granite® Storm and Granite® HDXtreme on Z275, except for sandwich panels|
These products are in compliance with standard EN 10169.
