Подробное описание

Описание товара

MT-D2525 Brilliance 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 Brilliance 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. The MT-D2525 Brilliance series being part of MT-D2525 range is awarded the prestigious Qualicoat Class 2 approval for ultra-durable architectural powder coatings and conforms to the requirements of EN12206 and EN13438 (high durability systems), GSB Master and AAMA 2604. Some colours may not be available in MT-D2525 Matt. Following RAL shades are excluded from the RAL families for Qualicoat Class 2: RAL 1003. 1028. 1033. 2004. 2011. 3015. 3017. 3018. 4001.

Предварительная обработка

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. Galvanised steel requires surface preparation by either multi-stage pretreatment using either zinc phosphate or chromate conversion or controlled sweep blasting. Depending on the type of galvanizing, degassing or use of anti-bubbling additives may be required – follow the procedural advice of the pretreatment 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.

Заполнитель

Powders can be applied by manual or automatic electrostatic spray equipment. All powders can show small color differences from batch to batch, this is normal and unavoidable. Differences are more likely with special effect powders. We recommend the use of flat jet spray nozzles. The use of direct box feed equipment may not reproduce fully the finish of our color standard. The use of direct feed equipment, by pumping into the box, may not fully reproduce the expected rendering of our standard color. This equipment could be responsible for a heterogeneity of surface aspect (marble aspect). To ensure homogeneity of the finish, completely empty the contents of the box in a fluidized bin. Only one pass and one batch should be used for items that will be simultaneously visible after assembly/installation. For manual application it is essential to ensure that a uniform film thickness is applied. Unused powder can be recovered and recycled on most common equipment subject to normal controls on ratios of recycled to virgin powder.Different substrates (aluminium, steel, galvanized steel…), use of primer, and big changes in film thickness may give a different aspect (marble aspect). 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. A constant ratio between virgin and recycled powders should be fixed by the coater in order to achieve a consistent effect.Products with different codes should not be mixed even if same colour and gloss.
