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.

MT-Active is suitable for corona electrostatic spraying.
| Girekomenda nga gibag-on sa pelikula | 60-80 µm Ang usa ka maayo nga proteksyon nalambigit sa girekomendar nga gibag-on sa pelikula. |
| pag-recycle | 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. |
