What Is a Zinc Flake Coating Applicator?2026-05-05T09:32:19-04:00

A zinc flake coating applicator specializes in applying non-electrolytic (non-electroplated) zinc aluminum flake coating systems engineered to protect fasteners and metal components from corrosion without hydrogen embrittlement. Depor is a U.S.-based zinc flake coating applicator and Magni subsidiary supporting automotive OEMs and Tier 1 suppliers with high-volume, quality-controlled production capabilities.

What Are the Advantages of Magni Zinc Flake Coatings Over Zinc Plating or Hot Dip Galvanizing (HDP)?2026-05-05T09:32:02-04:00

Magni zinc flake coatings are frequently specified as an alternative to zinc electroplating and HDG in applications requiring controlled friction coefficients, uniform coating thickness, and high corrosion resistance without hydrogen embrittlement risk. Unlike electroplated zinc, Magni coatings are non-electrolytic systems that eliminate hydrogen exposure during application, and compared to HDG, they provide more consistent film build on threaded fasteners while meeting demanding automotive and industrial corrosion performance specifications.

What Are Dip Spin Coating Services?2026-05-05T09:31:43-04:00

Dip spin coating services are high-volume coating processes where fasteners are immersed in zinc flake coating and spun to achieve uniform coverage and controlled film thickness. Depor provides dip spin coating services for automotive and industrial fastener coating programs requiring corrosion resistance and torque-controlled performance.
