Zinc phosphate conversion chemistry: HenkelRecent Research Landscape

Corrosion-prone metallic surfaces in high-volume production lines suffer from poor paint adhesion and premature oxidation. These innovations utilize multi-stage chemical activation to engineer a dense crystalline phosphate layer that stabilizes the substrate.

What technical problems is Henkel addressing in Zinc phosphate conversion chemistry?

Inadequate substrate corrosion resistance

(26)evidences

Variations in substrate composition during series processing lead to non-uniform coating formation. Standardizing reactivity ensures predictable corrosion protection across diverse metallic components.

Surface coating chemical instability

(7)evidences

Zinc and zinc alloy coatings are prone to rapid oxidation and white rust formation when exposed to environmental moisture. Preventing this degradation maintains the structural integrity and aesthetic quality of the substrate.
