MT-200 Cr is a series of polyurethane-based powder coatings designed for the exterior environment offering excellent corrosion resistance and flexibility properties. Exceptionally smooth flow and high gloss make MT-200 Cr powders ideal for applications where a high level of aesthetic finish is required. Please note that MT-200 Cr are not designed for architectural applications. To prevent oxidation of the basecoat, a clear coat must always be applied.

Iron phosphate and particularly Zinc phosphating of ferrous metals improves corrosion resistance. Aluminium substrates may require a chromate conversion coating. Aluminium components should receive a full multi-stage chromate conversion coating or suitable chrome-free pre-treatment or suitable pre-anodising to clean and condition the substrate. Detailed advice should be sought from the pre-treatment supplier.
Bonded products have better application properties than blended products (more stable) but attention should still be paid to line settings in order to avoid “marble effect” and changes in aspect after recycling. Products with different codes should not be mixed even if same colour and gloss. Different substrates (aluminium, steel, galvanized steel…), use of primer, and big changes in film thickness may give a different aspect. It is recommended that for consistent application and appearance product be fluidized during application. Powders can be applied by manual or automatic electrostatic spray equipment.
The results are based on mechanical and chemical tests which (unless otherwise indicated) have been carried out under laboratory conditions and are given for guidance only Testing has been determined under laboratory conditions using the following application properties and is for guidance only. The test results are shown below based on a single layer application of MT-200 Cr without application of a clearcoat.
