High Performance Powder Coating Primer

High Performance Powder Coating Primer About

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 m / Ra 6-12 m	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 m 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 m / Ra 6-12 m	Banned

Application

MT-Active is suitable for corona electrostatic spraying.

Recommended film thickness	60-80 m 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 80 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.
