UV absorbers are used in clear unpigmented top coats to enhance the durability of the coating and provide protection to the base coat in clear over base systems. The UV absorber system is made up of a UV absorber, normally of the benzotriazole or oxalanalide type and a hindered amine light stabiliser (HALS). The most commonly used commercial UV absorbers are the Tinuvin range of products from Ciba Geigy, the Sanduvor range from Sandoz, and Cyasorb from American Cyanamid.
