DFBE Coating Plants

Dual fusion bonded epoxy with abrasion-resistant overcoat

DFBE Coating System Overview

DFBE (Dual Fusion Bonded Epoxy) is an advanced coating solution that adds an abrasion-resistant overcoat (ARO) layer of 100-200 microns on top of standard FBE primer. This dual-layer system delivers enhanced mechanical protection for applications where rocky backfill, aggressive handling, trenchless installation, or subsea conditions create risks of coating damage.

The ARO layer provides exceptional impact and gouge resistance while maintaining the proven corrosion protection properties of FBE. DFBE is the ideal choice when you need both thermal protection and mechanical durability in a single, cost-effective coating solution. Fully compliant with ISO 21809-2 standards.
