Paint defects


What is the origin of a stain observed on the surface of a bottle of cosmetic cream?


Materia Nova is able to identify the composition of the contamination responsible of the defect.

The appearance of a defect on a coating can be explained in various ways:

  • Exposure to an aggressive substance (solvent),
  • External pollution,
  • Corrosion,
  • Misapplication or annealing problems,
  • ...


In this situation, the observation by electron microscopy (SEM) can exactly localize the surface defect, indicating external contamination.

The ToF-SIMS spectrometer identifies this contamination as a perfume contained in the cream.
