Peka‑Pro DL‑UF (Dual Layer Ultra‑Flexible FBE Coating)

About

Dual‑layer Fusion Bonded Epoxy (FBE) system engineered for exceptional flexibility at high film thickness, ideal for pipelines requiring tight bends without compromising corrosion protection.

More info from this product

Peka‑Pro DL‑UF from Peka Chemie is a specialized dual‑layer FBE coating system designed to meet or exceed the CSA Z245.20‑22 System 2A flexibility requirements. This coating is formulated for pipeline sections that must undergo significant bending during installation — such as when navigating terrain changes, river crossings, or challenging alignment profiles.

By combining the proven Peka‑Pro Pr primer layer for corrosion resistance with a specially modified ultra‑flexible FBE topcoat, DL‑UF ensures that pipes can be bent further than with conventional FBE systems, even at higher film thicknesses. This flexibility is achieved without sacrificing adhesion, abrasion resistance, or long‑term durability.

Key Advantages

  • Outstanding flexibility, exceeding CSA System 2A specifications
  • High bending capability without surface cracks or coating failure
  • Maintains excellent corrosion and cathodic disbondment resistance
  • Ideal for HDD, side‑booms, or terrain‑driven bending installations
  • Proven performance in both onshore and offshore pipeline projects

Application Process

  1. Blast clean steel to Near‑White (SA 2½, ISO 11124‑3), profile 50–100 μm
  2. Preheat substrate to 218–250 °C
  3. Apply corrosion‑resistant Peka‑Pro Pr primer (400 ± 50 μm)
  4. Apply ultra‑flexible DL‑UF topcoat (450 ± 50 μm)
  5. Controlled cooling to lock in coating integrity and flexibility
