Physical properties Melting range 120 – 150 °C Flashpoint not tested Specific gravity (20 °C) 1.01 g/cm³ Dec 18, 2017 · SONGSORB® CS 81 by Songwon is 2-hydroxy-4-n-octoxybenzophenone. Acts as a solid UV absorber. It absorbs ultraviolet radiation in the 240~340nm region. Significantly improves the resistance of clear coating against discoloration, cracking, loss of gloss and loss of adhesion. Exhibits synergy with HALS. Chimassorb® 81 FL by BASF is a benzophenone grade. Acts as a UV absorber. Imparts good light stability when used in combination with hindered amine light stabilizer (HALS) of Chimassorb®, Tinuvin® or Uvinul® range. Protects a number of other polymers against degradation caused by light exposure such as plasticized PVC and rubbers. CHIMASSORB 81 also protects a number of other polymers against degradation caused by light exposure such as plasticized PVC and rubbers. CHIMASSORB 81 can be used in combination with antioxidants, phosphites and light stabilizers. Features/benefits CHIMASSORB 81 is particularly suitable for thick films, typically > 100µm and thick sections. The
