CONTEXT
It is widely known that, under normal conditions and as
a consequence of sun-related ultraviolet light, advertisement signs undergo deteriorations.
To avoid this phenomena, micrometric layer of varnish are usually applied.
Nevertheless, ultraviolet light also deteriorate said varnish. A solution to this matter is therefore to give said varnish anti-ultraviolet
filtration property by adding nanoparticles based on Titanium dioxide.
Unfortunately addition of
nanoparticles in varnish or in any organic medium always leads to phenomenon of
bulking and precipitation giving said medium
heterogeneous and opaque aspect.
