Hypothesis
Alkyd-based paints may undergo hydrolysis processes leading to the formation of metal soaps.
Conclusion
The study confirmed the formation of metal soaps in both mock-up and real alkyd-based paints.
Supporting Evidence
- The study confirmed the formation of metal carboxylates in mock-up paints.
- FTIR analysis showed the presence of metal soaps in both mock-up and contemporary artworks.
- Different reactivity was observed for the materials based on the cations' availability.
Takeaway
This study looked at how certain paints can form metal soaps over time, which can affect their appearance and stability.
Methodology
The study involved preparing mock-up paints with an alkyd binder and analyzing them using FTIR spectroscopy.
Limitations
The study primarily focused on a limited number of pigments and mock-up paints, which may not represent all alkyd formulations.
