Abstract

New partially fluorinated acrylic copolymers, purposely synthesised for the protection of cultural heritage stone materials, are applied on stone specimens, tested in laboratory and evaluated in comparison with two very well known commercial products employed in the field. The new materials are synthesized from different co-monomers tailoring the final properties of the macromolecules such as film-forming behaviour, adhesion to the substrate, water repellency, and long term photostability. Several copolymers of fluorinated acrylates and methacrylates with unfluorinated methacrylates and vinyl ethers have been evaluated both for their intrinsic chemical stability under UV ageing conditions and for their protective efficacy. The introduction of fluorine allows to improve the protection performance of methacrylic copolymers and to enhance their UV resistance, overall in the case of application on high porous substrates
