Imparts good light stability & UV protection to a wide variety of polymers such as styrene homo- and co-polymers, polyesters, cellulose esters, epoxy, elastomers, acrylic resins, polyurethanes, polyvinylchloride and polyacetals. It features a very strong absorption band between 300 – 400 nm and also exhibits a high degree of photo-stability over long periods of light exposure. Can be used alone or with other additives such as hindered light stabilisers and antioxidants where more often than not a synergistic performance can be observed. Used in adhesives.
