Light Stabilizer 770 With Excellent Light Stability For Thick Sections And Films
Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer that provides
excellent light stability for thick sections and films in the recommended substrates.
Feather of Light Stabilizer 770
Excellent light stability for thick sections and films in the recommended substrates.
High light-stabilizing performance,particularly in PP thick sections.
Broad compatibility and can be easily dispersed.
Compared to conventional UV-absorbers,the effectiveness of LS770 is less dependent on the polymer's thickness.
Provides good light stability in articles with higher specific surface,e.g.films and tapes.
