Powder coating primer

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.

Cast steel
Electro Zinc steel	Sweep blasting with a maximum zinc layer thickness reduction of 5 to 10 m depending on the initial zinc thickness
Hot dip galvanized stee	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

Exceptional Corrosion Resistance

Our powder coating primer is formulated to deliver high corrosion resistance, making it ideal for usage in demanding industrial settings where metal surfaces are exposed to harsh environments. This ensures long-lasting protection and durability for those critical assets.


User-Friendly Application Process

Engineered for simplicity, the primer is ready to use without any mixing, making application seamless. Whether using electrostatic spray guns or fluidized bed techniques, the powder provides even coverage and excellent adhesion to metals with minimal preparation.


Versatile Finishes and Color Choices

Choose from smooth, glossy, matte, or textured finishes and a wide color range based on the shade card. The flexibility in appearance options allows users to match precise aesthetic and functional needs for a variety of projects.
