Electrochemical Impedance Spectroscopy (EIS) is a powerful and sensitive tool to detect the condition of a coated metal.  This technique can generate quantitative data relating to the quality of a barrier coating and the plot of data can be used to indicate the status of coating long before any visible damage occurs.  EIS can also be used as a post-evaluation tool to indicate the barrier property or any change in the coating after the test exposure, such as QUV exposure, Autoclave test, Atlas Cell test, Salt Fog or Immersion test, etc.  Examination of the cross section for porosity/voids in the coating vis optical microscopy.  High levels of porosity can lead to internal weakness and stress cracking (can also obtain film thickness at the same time, SEM/EDXA of the underside to look for potential contamination such as chlorides, DSC to determine Tg and residual exotherm of cure, IR for positive material identification with comparison to reference authentic material, Nitrogen Analysis for base to hardener Mix ratio.

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.
