July 14 2025

Proven in Oil & Gas, Petrochemical, and Refining Industries Worldwide

Reliable Corrosion Protection

  • 10–15+ year lifespan in aggressive process environments
  • 30–50% cost savings vs. weld overlay or component replacement
  • Fast application rates for large surface areas (3-6m2/shift/machine)
  • Maintains wall thickness and asset integrity
  • No need for PWHT or curing time. Back in service immediately.
  • Predictable performance even in high-H₂S, chlorides, or CO₂ atmospheres
