Akzo Nobel Webinar on Reducing the Cost of Corrosion Under Insulation (CUI)  Wednesday, October 30, 2019 entitled:
CUI Miitigation – Reduce Risk, Improve Productivity –  A Technical Comparison between Traditional Coating Technologies and Alkylated Amine Epoxy Technology for CUI Mitigation.
by George Sykes (Product Manager, Oil & Gas Akzo Nobel) and Ana Sanseau-Blanchard (Technical Specialist, Marine Protective Coatings R& D Akzo Nobel) 
When applied properly it (Epoxy Phenolic) shows good resistance to corrosion under insulation. Unfortunately it (Epoxy Phenolic) does present some challenges for large complicated projects.  If the EP coating does not cure than that is where your CUI will start and it will compromise the whole system. EP coatings can be slow drying and very sensitive to over application.  EP coatings are particularly sensitive to over application of DFT.  When the asset is put into service and when it heats up your very likely to see cracking if the paint has been over applied.  We asked ourselves the question how do you apply a DFT sensitive coating like an epoxy phenolic to a wide variety of pipes, valves and vessels?….and the answer is that it is really, really hard.  In real life when people are moving quickly maybe to increase productivity especially coating something like a valve I think it is almost impossible to get a DFT within the very narrow confines that is required for a traditional epoxy phenolic. In the field EP coatings are increasingly being specified without a durable topcoat or insulation.  A combination of extreme UV and very heavy rainfall has actually had an erosive effect on the EP coating leading to reduced anticorrosion protection………more

This newsletter is brought to you by ExcelPlas Coating Labs (

ExcelPlas Labs provides independent testing, analysis and investigation on protective coatings to prevent corrosion.

ExcelPlas has extensive analytical capabilities for testing of Protective Coatings and Insulation Consulting for major oil and gas companies.

We conduct corrosion surveys, coating sampling, coating analysis and testing to ensure coating specifications for a wide range of onshore and offshore clients in Australia and the Asia-Pacific Region.

ExcelPlas Labs offer a full range of coating testing and analytical services to Australia’s mining, oil, gas and infrastructure sectors.

Forensic analysis for undertaking various coating based failure investigations and problem solving.

ExcelPlas Undertakes Analysis & Testing of Polymer Coating Systems including:
• Epoxy Protective Coatings
• Epoxy-Phenolic Protective Coatings
• Fusion bonded epoxy (FBE) 
• Dual-Layer Fusion bonded epoxy (DLFBE)
• Liquid applied epoxy (LAE)
• Abrasion resistant overcoat (ARO)
• Three-layer PE (3LPE)
• Multi-component liquid spray  (MCL)
• Heat shrink sleeves (HSS)

Testing on Coatings that ExcelPlas can Undertake includes:
• Coating identification by Infra-red Analysis (FTIR)
• Degree of Cure by Thermal Analysis (DSC)
• Coating Filler Identification by X-ray Analysis (EDS/XRD)
• Coating Microstructure by Embedding, Polishing and Optical Microscopy (OM)
• Coating Thermal Stability and Composition by Thermogravimetric Analysis (TGA)

DSC – Phase transition/volatiles / Tg / degree of cure/characterisation
TGA – Volatile compounds, inorganic mass % mix ratio
Element mapping for chlorides on paint flakes
Microscopy -Count layers and thickness of layers
-Assess porosity and voids
-Check distribution and orientation of filler particles

Condition monitoring and analysis of corrosion prevention coatings (epoxies, epoxy-phenolics)

Testing of Epoxy Coatings (LAE, FJC, FBE), heat shrink sleeves and tapes, barrier tapes and meshes.
