What Is a Zinc-Flake Coating?
Zinc-flake coatings provide high-performance corrosion protection for metal components by combining layers of microscopic zinc and aluminum flakes with a protective binder system. Unlike traditional zinc plating, zinc-flake coatings are typically applied as a dip-spin or spray process, allowing them to provide excellent coverage—even on complex shapes and threaded components.
The zinc flakes create a highly effective barrier against corrosive elements while also providing sacrificial protection to the underlying steel. The result is durable corrosion resistance, controlled coating thickness, and reliable performance for demanding automotive, industrial, and manufacturing applications.
Why Zinc-Flake Coatings?
Corrosion Protection | A combination of barrier protection and sacrificial protection
Thin, Consistent Coating | Important for threaded and precision components
No Hydrogen Embrittlement | Excellent option where hydrogen embrittlement is a concern
Controlled Friction & Torque | Can provide controlled coefficient of friction and torque performance
Complex Parts | Dip-spin application allows the coating to reach difficult areas
The Takeaway
It is an engineered coating system designed to protect steel components while maintaining dimensional control, assembly performance, and long-term durability. With options for different coating and topcoat systems, zinc-flake technology can be tailored to meet demanding corrosion, friction, appearance, and regulatory requirements.
