Powder Coating Primer Mt Active El140n - China

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.

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.
