Uses: It is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability
for plastics and other organic polymers. UV-P protects polymers as well as organic pigments
from UV radiation helping to preserve the original appearance and physical integrity of engi-
-neered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering.
