Leadstab UV 3638 is a highly efficient and non-staining UV absorber, covering both of UV-B and UV-C regions up to 400nm. It based on benzoxaxinone structure which delivers a sort-term heat stability up to 350°C and a long term heat stability up to 160°C. By a proprietary process, Leadstab UV 3638 is made to dissolve quickly in PET resin and to give a transparent appearance even with high dosage. Due to these non-staining and transparent properties, Leadstab UV 3638 is ideal for film/sheet/plate applications such as solar cell, window film etc. Furthermore, Leadstab UV 3638 can be used for food contact applications such as PET bottles and food wrap films.
