15 of the Most Common Causes of Failure of Protective Coatings & the Type of Failure (from ExcelPlas 25 Years of Experience)

  1. Inadequate blasting and insufficient removal of mill scale from the steel leading to poor adhesion
  2. Use of blasting grit with soluble salt contamination leading to osmotic blistering and under film corrosion
  3. Oil contaminated compressed air used for blasting leading to surface contamination leading to poor adhesion and delamination of the coating
  4. Inadequate blast profile i.e. shallow valleys leading to poor adhesion
  5. Excessive blast profile i.e. high peaks leading to poor steel coverage and risk of rust-rash corrosion, particularly for low DFT coatings.
  6. Excessive delay between blasting and coating causing flash corrosion contamination leading to poor adhesion and corrosion cells
  7. Addition of too much thinner that increases the potential for porosity and pinholes in the coating. There is also an increased propensity for the formation of Bernard Cells where there are boundaries of resin rich coating, resulting in “crows feet” cracking.
  8. Poor mix ratio of the epoxy with the hardener leading to incomplete cure
  9. Inadequate mixing/stirring of the coating before application leading to poor distribution of barrier pigments leading to coating cracks and premature corrosion
  10. Inadequate coating specification: lack of suitable topcoat for UV sensitive epoxies leading to chalking and UV breakdown
  11. Inadequate curing of coatings leading to less than optimal properties of the coating with increased moisture penetration and formation of corrosion cells
  12. Incompatibility of coating if different paint systems are used multicoat application leading to delamination/peeling
  13. Poor QA leading to inadequate control of coating thickness (e.g. excessive DFT) leading to cracking of the coating due to residual stresses
  14. Poor QA leading to inadequate control of coating thickness: low coating thickness or missing coats can lead to poor barrier performance and premature corrosion
  15. Exceeding the recoat window leading to delamination of topcoat from primer coat due to blast-dust contamination or lack of interfacial adhesion.

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

Condition Assessment of Protective Coatings – Coating Inspection & Damage Assessment
ExcelPlas Labs have been serving the gas, oil and water industries for the past 20 years within Australia, New Zealand and Oceania. The company is a major testing provider to the pipeline and LNG industry.  Whether you’re an engineer, consultant, pipeline owner, pipeline operator, LNG facility or construction company, ExcelPlas Labs can conduct a range of analytical testing on protective coatings to assess their condition, integrity and durability.  ExcelPlas Labs have extensive in-house coatings testing equipment such as DSC, FTIR, TGA, TMA, EIS, SOM, XRD, QUV etc.

ExcelPlas Coating Labs – The Leaders in Evaluation and Assessment of Protective Coatings 
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.
