Phosbond

Conversion coatings engineered for paint adhesion and corrosion resistance.

Overview

Phosphate coatings

Phosbond is our range of iron, zinc and tri-cation phosphating systems that build a fine, crystalline conversion layer on ferrous metal — the ideal base for paint, powder coat, or oil-based rust prevention.

Run as a spray or dip process, Phosbond systems are formulated for low operating concentration and consistent crystal structure batch after batch.

Key Benefits

Why processors choose Phosbond

🎨

Superior Paint Adhesion

A crystalline conversion layer that gives paint and powder coat something to bond to.

🛡️

Corrosion Resistance

Improves salt-spray performance under painted and unpainted finishes alike.

⚗️

Low Concentration

Efficient bath chemistry that keeps operating and disposal costs in check.

💧

Spray & Dip Ready

Formulated for both spray-stage and immersion phosphating lines.
