Advanced Zinc-Polymer Composite Coatings for Marine Corrosion Protection and Self-Healing
Steel corrosion in saltwater costs over $2.5 trillion annually. This review highlights advancements in zinc and polymer-based coatings for marine protection
Three birds with one stone: multi-functional interface strengthening to construct self-warning smart coatings with integrated corrosion and fouling resistance
Interface defects can significantly diminish the protective performance of a system. Specifically, coating aging is accelerated markedly by UV radiation, high temperature, high humidity, and microbial attack. To address these issues, this study develops a functional integrated intelligent coating with anti-corrosion and anti-fouling capabilities (SCC/ZPhP) via interfacial reinforcement and multi-component composite engineering.

COATINGS FAILURE ANALYSIS
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.

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?
