Paint/Coating Testing & Failure Analysis

A significant amount of financial loss is incurred every year as a result of premature failure of protective paints and coatings. The cost to repair such failures far outweighs the initial cost of painting due to the extreme cost and liability associated with excessive rigging and downtime to correct the problem.

The majority of paint and coating-related failures can be attributed to following causes:

  • Improper surface preparation – the substrate surface is not adequately prepared for the coating that is to be applied. This may include cleaning, chemical pretreatment or surface profile.
  • Improper coating selection – either the paint or coating selected is not suitable for the intended service environment, or it is not compatible with the substrate surface.
  • Improper application – this can be a problem with either shop-applied or field applied coatings, and occurs when the required specifications or parameters for the application are not met.
  • Improper paint formulation,  drying, curing and over coating times –this problem relates to a lack of conformance to the required specifications or parameters.
  • Lack of protection against water and aqueous systems – this is a particularly serious problem with aqueous systems containing corrosive compounds such as chlorides.
  • Mechanical damage – which results from improper transport, handling of the painted or coated substrate, resulting in a breach in the paint or coating.

Matergenics’s Coatings and Analytical Chemistry Division can resolve coating failures through techniques such as:Fourier transform  infrared spectroscopy(FTIR); scanning electron microscopy/energy dispersive x-ray spectroscopy; light microscopy; electrochemical impedance spectroscopy(EIS); chromatography; thermal analysis and wet bench testing. Matergenics performs a wide array of standard ASTM, SSPC and NACE test procedures.

surface profile measurementIn paint failure analysis investigations, our NACE/SSPC certified Coating Specialists will keep you informed of results as they become available. Each failure analysis investigation will include a formal report containing the description of the defect, review of the application and exposure conditions, laboratory analysis to check against specifications, on-site and analytical test results, factors influencing the paint failure, identification of failure mechanism and root cause, related problems, and corrective actions if requested.
