Exploring Epoxy Coating Failures with ExcelPlas Labs
While epoxy coatings are generally durable and effective at preventing corrosion, there are a few common types of epoxy coating failures that can occur:

  • Adhesion failure: This occurs when the epoxy coating fails to properly adhere to the surface of the pipe, which can be caused by factors such as improper surface preparation or a poorly formulated coating. Adhesion failure can result in the coating peeling or flaking off, exposing the underlying steel surface to corrosion.
  • Blistering: This occurs when small bubbles or blisters form on the surface of the epoxy coating, which can be caused by improper surface preparation, moisture contamination, or excessive heat during curing.
  • Cracking: This occurs when the epoxy coating develops small cracks, which can be caused by factors such as thermal expansion and contraction, improper coating thickness, or exposure to chemicals.
  • Delamination: This occurs due to intercoat or interfacial adhesion failure due to the presence of a weak boundary layer such as silicone or hydrocarbon oil contamination.


Failure Analysis and Investigation of Protective Coatings in Mining, Marine Offshore Oil & Gas Chemical Plants, Energy Infrastructure and Bridges (Ask the Experts)

Critical Questions for Protective Coatings for Asset Protection in Oil & Gas, LNG:

  • Why is the coating not stopping corrosion?
  • Why is the coating delaminating or blistering?
  • Has the coating been correctly specified / applied?
  • Does the coating meet the manufacturing standard, including properties such as correct hardness/cure, adhesion and thickness?
  • What surface preparation and atmospheric conditions must be achieved to successfully apply the coating?
  • Does the coating have any defects in it? How will these affect performance?
  • Why did the coating fail? Root cause assessment.
  • How can the coating be successfully repaired/remediated so that it doesn’t fail again?

ExcelPlas Labs can answer these questions and more…
