Our Doerken Delta coating service applies Dorken DELTA and DELTA-PROTEKT zinc flake systems to fasteners and precision metal components for high corrosion protection at low coating thickness. This non-electrolytic coating process combines an inorganic zinc flake basecoat with an optional topcoat to improve chemical resistance, friction control, and surface appearance. It is widely used where components need uniform coverage on complex geometries, dependable outdoor durability, and corrosion protection without the hydrogen embrittlement risk associated with electroplating.
