Damage to coated surfaces has high financial consequences and therefore the causes of such damage must be identified.

Causes of damage to coatings

Damage to coatings and coated surfaces has diverse causes:

  • Defective substrate materials
  • Inadequate cleaning
  • Insufficient pre-treatment
  • Defective coating materials
  • Shortcomings with the coating process
  • Mechanical stresses/loads
  • Environmental effects

Damage/failure analysis, expert appraisal/reports, and damage alleviation

The Paint/Lacquer Technology specialists at Fraunhofer IFAM are your ideal partners for determining the causes of coating damage/failure and for the preparation of expert reports. Various methods are used here to systematically record, limit, and, if necessary, simulate the causes and their origin. Damage/failure analysis involves appraisal by a technical expert who identifies and appraises the causes of the damage/failure using a wide range of analytical methods.

The services of the Paint/Lacquer Technology group include not only determination of the cause of the damage/failure but also the preparation of a customer-specific range of measures for alleviating or preventing the damage/failure.
