Pre-treatment

For maximum protection it is essential to pretreat components prior to the application of mt- D2525. 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. MT-D2525 products may also be used on cast or mild steel. For outdoor use MT- PZ anti-corrosive primer over a correctly prepared substrate is recommended.

Application

MT-D2525 powders can be applied by manual or automatic electrostatic spray equipment. For solid shades, unused powder can be reclaimed up to a maximum of 30% using suitable equipment and recycled through the system. MT-D2525 powders should be applied at minimum 60µm. All powders can show small color differences from batch to batch, this is normal and unavoidable.  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. 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. For more information, it is suggested to read the Metallic Applications Guidelines. Products with different codes should not be mixed even if same colour and gloss.
