Product Description
MT-Active is a powder coating primer, totally free from Zinc. It is designed to give enhanced corrosion protection of mild steel and is an epoxy-polyester primer including active anticorrosive pigments. The addition of these pigments provides a steel passivation effect to protect the substrate enhancing the performance when compared to other non-active systems.

Pretreatment
Surface preparation depends upon the metal, the type of surface, its conditions and the required performance.
| Substrate | Mechanical pretreatment | Chemical pretreatment |
| Mild steel | Grit Blasting Sa 2.5 in accordance with ISO NF EN 8501-1. Roughness: Rz 42 84 µm / Ra 6-12 µm | Degreasing & phosphating (or equivalent) followed by passivation, DW rinsing and drying. |
| Cast steel | ||
| Electro Zinc steel | Sweep blasting with a maximum zinc layer thickness reduction of 5 to10 µm depending on the initial zinc thickness. | |
| Hot dip galvanized steel | Degreasing & phosphating / chromating followed by passivation. | |
| flame/electrical deposition) | Grit Blasting Sa 3 in accordance with ISO NF EN 8501-1. Roughness: Rz 42 84 µm / Ra 6-12 µm | Banned |
Application
MT-Active is suitable for corona electrostatic spraying.
| Recommended film thickness | 60-80 µm A good protection is linked with the recommended film thickness. |
| Recycling | For marine applications, related to cycles approved RINA / DM, the thickness of the metal support must be> = 0.6mm, and the thickness of the coating film must respect the value of 80μ ± 10%. Unused powder can be reclaimed using suitable equipment and recycled through the coating system, but a minimum of 70% new powder should be used. |
Types of powder coating
Powder coatings can be categorized by resin system (epoxy, polyester, hybrid, polyurethane), appearance (smooth, texture, hammer, metallic, pearlescent), or performance level (anti-corrosion, heat-resistant, UV-resistant, architectural grade, automotive grade).
Powder coating colours and effects
Powder coatings offer thousands of colors in gloss, matte, satin, metallic, candy, texture, wrinkle, hammer tone, wood grain, fluorescent, and other custom effects. Special powders can create soft-touch, anti-scratch, anti-fingerprint, or anti-graffiti surfaces.
Powder coating process
The process generally includes surface pretreatment (degreasing, phosphating, chromating, sandblasting), drying, electrostatic spraying, curing in an oven, and cooling. A well-controlled pretreatment and curing process ensures strong adhesion and long service life.
Powder coating benefits
Powder coatings are environmentally friendly, solvent-free, and produce minimal waste. They offer excellent corrosion resistance, weather durability, mechanical strength, and uniform film appearance. The coating is tough, impact-resistant, scratch-resistant, and has a long lifespan.
Applications for Powder Coatings
Powder coatings are widely used in appliances, aluminum profiles, architectural components, automotive parts, bicycles, furniture, outdoor equipment, machinery, electrical cabinets, pipeline systems, and general industrial and consumer goods.
