Pre-treatment

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-PZ anti-corrosive primer over a correctly prepared substrate is recommended.

Application

Powders can be applied by manual or automatic electrostatic spray equipment. This product should be applied at minimum 60m. 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. Different substrates (aluminium, steel, galvanized steel), use of primer, and big changes in film thickness may give a different aspect. 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. For more information, it is suggested to read the Metallic Applications Guidelines. Clearcoats including tinted clearcoats cannot be applied directly on primers. Only fully opaque shades are suitable for application over primer.

Application Method	Electrostatic
Recycling	For solid shades, unused powder can be reclaimed Unused powder can be reclaimed using suitable equipment and recycled through the coating system, but a minimum of 70% virgin powder should be used.

Post application

For specific advice on the suitability of post coating processes such as bending or the use of sealants, adhesives, thermal break, cleaning etc. Please consult us.

Superior Weather and Corrosion Resistance

Engineered for environments demanding exceptional durability, these polyester powder coatings are highly resistant to harsh sunlight (UV) and corrosive conditions. Their robust formulation safeguards metal surfaces from fading, chalking, and rust, making them ideal for exterior architectural elements and high-wear industrial structures.


Versatile Application and Finish Options

Choose from matt, semi-gloss, or glossy finishes to complement any design. The coatings adhere best to properly prepared surfaces-degreased, phosphated, or sandblasted-and are applied via electrostatic spray. The recommended film thickness ensures comprehensive coverage while maintaining visual appeal across various colors and custom shades.


Safe, Sustainable, and Certified Quality

Our powder coatings are formulated to be lead-free, non-toxic, and solvent-free, prioritizing both user safety and environmental responsibility. Manufactured to meet rigorous standards, such as Qualicoat, GSB, and ISO, they are supplied in secure HDPE bags or cartons with shelf stability of up to 12 months when stored below 25C in dry conditions.
