Peka‑Pro DL‑AS (Dual Layer Anti‑Static / Anti‑Slip FBE Coating)

Peka‑Pro DL‑AS from Peka Chemie is a hybrid functional coating system combining the benefits of enhanced anti‑slip texture with anti‑static capability. This dual‑layer FBE system is designed for steel pipelines requiring a concrete weight coating (CWC) in environments where electrostatic charge buildup must be mitigated — for example, in flammable gas service or installations in dry climates where static could cause safety hazards.

The base corrosion‑resistant FBE primer (Peka‑Pro Pr) provides long‑term cathodic disbondment resistance, while the outer anti‑slip / anti‑static layer improves shear resistance between the pipe and CWC, ensuring secure placement and preventing micro‑movement under load or buoyancy forces.

Key Advantages

• High‑friction surface prevents slippage between pipe and CWC
• Anti‑static formulation reduces surface resistivity to dissipate charge
• Maintains full FBE corrosion protection performance
• Compliant with CSA Z245.20‑22 System 2C requirements
• Ideal for subsea, river crossing, and flammable media pipeline projects

Application Process

1. Surface blast cleaning to SA 2½ (ISO 11124‑3), profile 50–100 μm
2. Preheat steel substrate to 218–250 °C
3. Apply Peka‑Pro Pr primer layer (400 ± 50 μm) for corrosion protection
4. Apply anti‑slip / anti‑static topcoat layer (450 ± 50 μm) with conductive fillers
5. Apply textured sealing layer (150 ± 50 μm) for friction enhancement and charge dissipation
6. Controlled cooling before CWC application
