Test Conditions

Testing has been determined under laboratory conditions using the following application properties and is for guidance only.

Substrate	Steel panels CRS ACT B958 P90
Pretreatment	Zinc Phosphate
Film thickness	330 380 (13 15 mils)

Actual film performance will depend on the individiual circumstances in which the product is used.

Pre-treatment

Steel surfaces to be coated must be clean and free from grease. For maximum protection it is essential to pre-treat components prior to the application of MT-A1242. Iron Phosphate and Zinc Phosphate of ferrous metals improve corrosion resistance.

Application

MT-A1242 powders can be applied by manual or automatic electrostatic spray equipment. It is recommended that for consistent application and appearance product be fluidized during application. Unused powder can be reclaimed using suitable equipment and recycled through the coating system.

Versatile Color and Gloss Options

Choose from an array of vibrant colors like blue, orange, green, black, brown, and silver, with gloss levels tailored from matt to high gloss. This adaptability allows manufacturers and suppliers to meet specific design and branding requirements across a variety of industrial applications.


Exceptional Performance and Durability

Formulated to withstand harsh environments, these powder coatings deliver excellent adhesion (5B), impact resistance (50 kg.cm), and superior UV and corrosion protection. Certified to ISO 9001, ASTM D3359, and Qualicoat standards, they ensure long-lasting protection for coil springs and suspension parts.


Safe, Eco-friendly, and Easy Application

With a non-toxic, lead-free formulation and an application method based on electrostatic spray (Corona or Tribo), these coatings are safe for users and the environment. Their stable, fine powder composition and convenient packaging make them easy to handle and store in cool, dry, ventilated areas.
