Fusion‑Bonded Epoxy Powder Coating (PE Three‑Layer Coating)

The PE Three‑Layer Coating system from Peka Chemie is recognized worldwide as one of the most effective pipeline protection technologies for oil, gas, and water transmission. This system integrates three functional layers to deliver unmatched resistance to corrosion, mechanical damage, and environmental stress throughout the pipeline’s service life.

• First layer: Fusion‑Bonded Epoxy (FBE) primer — provides a strong chemical bond to steel, outstanding corrosion resistance, and cathodic disbondment performance.
• Second layer: Copolymer adhesive — ensures a high‑strength bond between the epoxy primer and polyethylene topcoat.
• Third layer: Polyethylene (PE) topcoat — delivers mechanical impact strength, abrasion resistance, and a durable barrier against moisture, chemicals, and soil stress.

This triple‑layered barrier is suitable for buried, submerged, or above‑ground pipelines, and is engineered to comply with global pipeline standards.

Key Advantages

• Exceptional corrosion resistance and long‑term adhesion
• Proven mechanical protection during transport, handling, and installation
• Superior impact, abrasion, and penetration resistance
• Effective performance in both standard and harsh environments
• Compatible with high‑temperature service (with appropriate grade selection)

Application Process

1. Surface Preparation: Blast clean steel surface to Sa 2½ (ISO 8501‑1) with 50–100 µm profile
2. Primer Application: Apply Fusion‑Bonded Epoxy layer (200‑500 µm)
3. Adhesive Layer: Extrude or wrap copolymer adhesive onto cured primer
4. Topcoat Application: Apply molten polyethylene strip via extruder
5. Cooling & Inspection: Controlled cooling, followed by thickness, adhesion, and holiday test checks
