Exterior Durable Polyester Powder Coatings With Advanced Fluidity Mt 610af - China

Product description

MT-610 AF powder coatings are designed to offer users significant improvements in their application characteristics.

MT-610 AF is a range of polyester TGIC Free powder coatings designed for exterior exposure with good weather resistance from just one application.

The coatings sustain a longer lifespan and are available in a wide range of colors and finishes which allow your product to shine.

They can be sprayed on conventional equipment and are compatible with standard powders but give a more uniform coverage, and in particular give improved coverage in Faraday Cage areas.

Powders are available in a range of colours in gloss and reduced gloss finishes and are always custom matched to the user’ s requirements.

MT-610 AF offers not only beautiful aesthetics but also a performance to match.

It is ideally suited to a broad range of outdoor applications including outdoor furniture, playground equipment, signs, fencing, vending machines and general metal finishing.

Can also be used for indoor application if required.

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.

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

Aluminium substrates may require a chromate conversion coating.

Application

Powders can be applied by manual or automatic electrostatic spray equipment.

A good protection is linked with the recommended film thickness.

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.

Different substrates (aluminium, steel, galvanized steel…), 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 colour and gloss.

It is recommended that for consistent application and appearance product be fluidized during application.
