Bright 100 is a high molecular weight optical brightener (fluorescent whitening agent) of the thiophenediyl benzoxazole class, suitable for the optical brightening of polymers at all stages of processing.
UV-326 is an ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, which imparts outstanding light stability to plastics and other organic substrates.
UV-571 is a liquid ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class which imparts good light stability to a variety of polymers.
UV-81 is an ultraviolet light absorber (UVA) of the benzophenone class, imparting good light stability when used in combination with a hindered amine light stabilizer (HALS). It shows good compatibility with polyolefins and plasticized PVC. UV-81 significantly improves the resistance of clear coatings to failures upon exposure to sunlight such as discoloration, cracking, loss of gloss and loss of adhesion.
