Organic substrates such as coatings, inks, adhesives and sealants with aesthetic, protective and other functional properties are exposed to a variety of environmental and artificial factors such as solar radiation, humidity, temperature change, microbiological attack and air pollutants. Light- or heat-induced oxidation of organic materials is a complex radical process characterized by initiation, propagation, chain branching, autocatalytic chain and termination reactions. UV absorbers (UVA) prevent the degradation of both coatings and substrates by filtering out the harmful UV radiation during the photolysis cycle and before subsequent photo-oxidation can take place. This webinar will explore the mechanisms of stabilization and different molecular classes of UV absorbers and hindered amine light stabilizers, as well as how these molecules are used for the stabilization of coatings. Participants will be eligible to receive credit from SSPC.
