Light stabilizers
They are used to protect the polymer from the yellowing effect or degradation caused by the UV rays, reducing its absorption from the polymeric matrix and, then, also as a consequence, of aging rate.
Polysorb range includes products derived from benzotriazole/benzophenone and photo stabilizers (HALS – hindered amine light stabilizer).
Sterically bulky amines (HALS) and UV radiation absorbent molecules (benzotriazoles and hydroxyphenyleneltriazenes), protect inks, varnishes, adhesives and plastic films generally from degradation phenomena caused by sunlight.
Polysorb are used in several product sectors such as plastics, rubber, cosmetics, adhesives, inks, paints, coatings and so on for both water and solvent systems.
