Game Changer for Coatings Under Insulation
Corrosion under insulation (CUI) continues to be one of the key coating integrity challenges associated with insulated equipment. Copsys Intelligent Digital Skin detects and locates coating barrier damage or CUI hotspots in real time before corrosion damage can occur. The integrated impressed current cathodic protection within the coating creates an entirely new category of continuous sensor technology. Consisting of an epoxy resin with Copsys proprietary additives and proprietary polyamine hardener, Copsys Intelligent Digital Skin is the first technology to digitally detect and locate coating damage.

Exploring Epoxy Coating Failures with ExcelPlas
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.
COATINGS FAILURE ANALYSIS
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?
