Paint defects
Question
What is the origin of a stain observed on the surface of a bottle of cosmetic cream?
Expertise
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,
- ...
Solution
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.
