FAILURE PREVENTION OF PROTECTIVE COATINGS
15 of the Most Common Causes of Failure of Protective Coatings & the Type of Failure (from ExcelPlas 25 Years of Experience)
- Inadequate blasting and insufficient removal of mill scale from the steel leading to poor adhesion
- Use of blasting grit with soluble salt contamination leading to osmotic blistering and under film corrosion
- Oil contaminated compressed air used for blasting leading to surface contamination leading to poor adhesion and delamination of the coating
- Inadequate blast profile i.e. shallow valleys leading to poor adhesion
- Excessive blast profile i.e. high peaks leading to poor steel coverage and risk of rust-rash corrosion, particularly for low DFT coatings.
- Excessive delay between blasting and coating causing flash corrosion contamination leading to poor adhesion and corrosion cells
- 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 “crow’s feet” cracking.
- Poor mix ratio of the epoxy with the hardener leading to incomplete cure
- Inadequate mixing/stirring of the coating before application leading to poor distribution of barrier pigments leading to coating cracks and premature corrosion
- Inadequate coating specification: lack of suitable topcoat for UV sensitive epoxies leading to chalking and UV breakdown
- Inadequate curing of coatings leading to less than optimal properties of the coating with increased moisture penetration and formation of corrosion cells
- Incompatibility of coating if different paint systems are used multicoat application leading to delamination/peeling
- Poor QA leading to inadequate control of coating thickness (e.g. excessive DFT) leading to cracking of the coating due to residual stresses
- Poor QA leading to inadequate control of coating thickness: low coating thickness or missing coats can lead to poor barrier performance and premature corrosion
- Exceeding the recoat window leading to delamination of topcoat from primer coat due to blast-dust contamination or lack of interfacial adhesion.

The A, B, Seas of Corrosion Management with Marine Coatings
Maintenance due to maritime corrosion comes with a staggering price tag, almost $2.5 trillion per year globally. Proper maritime corrosion management results in a tangible ROI, improved safety, and an operational ability that aligns with existing mandates to address reasonable risks in decision making.
Chapters touch upon such topics as marine coating systems and antifouling topcoats, the loss of adhesion and delamination of ship coatings, the failure of a separator onboard a FPSO, and even the importance of not painting a structure during a windstorm!
