It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. It is used in polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA and polyurethanes and is also effective in polyamides and polyacetals. It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers, the effectiveness of it is less dependent on the polymer’s thickness.
Usage: 0.1% and 0.5%, depending on the substrate, processing conditions and application.

Toxicity and safety: It can be safely handled without any irritation to the skin.
Packing: Fiber drum or cardboard drum inner lining plastic bag, each drum 20kg net weight or as required by the customers.
Storage: It should be stored in a close system and kept in a dry, close and shade place.
