Pre-treatment

Steel surfaces to be coated must be clean and free from grease, mill scale and rust. For maximum protection, it is essential to pre-treat components prior to the application of MT-JA220G. Iron phosphate and zinc phosphate pre-treatment of ferrous substrates improve corrosion resistance. Aluminium substrates may require a chromate conversion coating.

Application

MT-JA220G can be applied using manual or automatic electrostatic spray equipment. It is recommended, that for consistent application and appearance, the product be fluidized during application. Unused powder can be reclaimed using suitable equipment and recycled through the coating system.

Versatile and Customizable Finish

MT-JA220G White offers versatility with options for glossy, semi-gloss, or matt finishes to match your specific design and functional requirements. Its excellent adhesion and wide compatibility with different metal substrates make it a preferred choice for both industrial and decorative uses.


Durability and Environmental Benefits

This polyester powder coating is highly durable, resistant to UV exposure, and corrosion. Formulated without solvents, it contains zero VOCs, promoting a safer and more sustainable work environment while extending the longevity of protected surfaces.


Efficient Application and Coverage

Applied via electrostatic spray, the powder coating achieves an even and consistent layer, optimizing material usage. With a coverage of up to 10 m2 per kilogram at 60 microns film thickness, it provides cost-effective protection and efficient processing in industrial settings.
