Hydrophobizing coatings for cultural heritage. A detailed study of resin/stone surface interaction

摘要: Conservation of historical buildings is an important issue and the environmental conditions seriously affect monument’s stones. The protection cultural heritage monuments by surface treatment with polymers a common practice due to their ability form protective layer on as well control transport different fluids from interior. In this work, three substrates were used: Carrara marble, Botticino limestone, Angera stone. A commercially available Si-based resin (Alpha®SI30) was used agent improve hydrophobicity features tested materials. properties coating relative interaction adopted stones studied using techniques such contact angle measurements, electron microscope coupled energy dispersive spectrometer, X-ray photoelectron spectroscopy, atomic force microscopy, attenuated total reflection infrared spectroscopy.
