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-MA220G. Iron phosphate and zinc phosphate pre-treatment of ferrous substrates improve corrosion resistance. Aluminium substrates may require a chromate conversion coating.

Application

MT-MA220G 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.

Exceptional Adhesion & Durability

Our polyester powder coating ensures excellent adhesion to all metal substrates, making it highly durable for industrial and architectural applications. Its film forms a tough, protective layer resistant to chipping, scratching, and deterioration from outdoor exposure, ensuring structures and components maintain their appearance and integrity over time.


Versatile Finishes & Application Methods

Choose from glossy, matt, or semi-matt finishes to achieve the desired aesthetic for your project. Application is flexible with options for both electrostatic spray and fluidized bed techniques, allowing precise control of film thickness and coverage for a flawless, uniform finish.


Environmentally Friendly & Safe to Use

This powder coating is formulated with a focus on environmental responsibility. It is non-toxic, VOC-free, and safe for operators. Storage requirements are straightforward-simply keep the product in a cool, dry, well-ventilated place to maintain its quality for up to 12 months from the manufacturing date.
