MT-D2525 Matt is a series of ultra-durable powder coatings specifically formulated without TGIC, intended for use on architectural aluminium and galvanized steel. Providing new levels of weathering resistance MT-D2525 Matt surpasses the performance of leading architectural powders. It offers significantly higher gloss retention and resistance to colour change combined with maximum film integrity to ensure long term cosmetic and functional protection. These powder coatings are classified in Family I – class 6c under standard NFT 36-005. MT-D2525 Matt meets the requirements of GSB Florida 3. Qualicoat Class 2. EN 12206 (formerly BS6496), EN13438 (formerly BS6497:1984) and AAMA 2604. Some colours may not be available in MT-D2525 Matt.

For maximum protection it is essential to pretreat components prior to the application of the powdercoating. 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. The products may also be used on cast or mild steel. For outdoor use MT-Redox PZ anti-corrosive primer over a correctly prepared substrate is recommended.
Powders can be applied by manual or automatic electrostatic spray equipment. This product should be applied at minimum 60μm. All powders can show small color differences from batch to batch, this is normal and unavoidable. 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. Applicators and fabricators are advised to use a single batch for parts that will be assembled together. Differences are more likely with special effect powders. Clearcoats including tinted clearcoats cannot be applied directly on primers. Only fully opaque shades are suitable for application over primer.
