Pretreatment

Aluminium, steel or Zintec surfaces to be coated must be clean and free from grease.

Iron phosphate and particularly lightweight zinc phosphating of ferrous metals improves corrosion resistance.

Aluminium substrates may require a chromate conversion coating.

Detailed advice should be sought from the pre-treatment supplier.

Application

MT-620 AM powder coatings can be applied by corona electrostatic equipment.

In all application processes the aspect obtained is subject to variation, depending on the method of application (type of gun, nozzle, etc) and the shape/type of component.

We recommend that the actual application parameters are adapted and adjusted depending on the type of component and with each powder batch to give a finish in accordance with our color card.

The following procedure is given as a guideline when using these finishes.

We recommend the use of flat jet spray nozzles.

To ensure powder homogeneity, the complete content of the boxes should be emptied completely into the feed hopper.

For manual application it is essential to ensure that an even film thickness is applied, and, in all Instances, sinusoidal gun movements should be avoided.

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 to avoid “marble effect” and changes in aspect after recycling.

Different substrates (Aluminium, steel, galvanized steel, etc.

), use of primer, and big changes in film thickness may give a different aspect.

Products with different codes should not be mixed even if same color and gloss.
