Polyester Powder Coatings For Indoor Use Mt 300 - China

Product description

MT-300 is a series of polyester resin based thermo-setting powder coatings formulated using TGIC.

The pigments used in the MT-300 series restrict the field of application of this powder coatings class to interior uses.

MT-300 is designed for interior decoration such as, metal furniture, shop fittings, shelves, light fittings.

8-16 min at 200°C 4-10 min at 210°C (at object temperature) Pre-treatment

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.

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.

MT-300 powder coatings can be applied by corona electrostatic or tribostatic equipment.

However, the aspect obtained by tribo static equipment may vary when compared to electrostatic application and/or our color card.
