Solar UV radiation has been shown to be one of the outdoor environment components deleterious to a variety of materials. These materials have
bond dissociation energies on the wavelength region of UV radiation (280 - 400 nm), leading to a complex set of processes at UV exposure and appearing as photodegradation
with the following signs:
o loss of surface gloss;
o flaking of surface resin;
o severe loss of resin from outer surface.
In essence, adverse effects of UV radiation considerably limit the lifetime of these materials.
