Siwin-LS944
Light stabilizer
The Light Stabilizer 944 is a type of high molecular weight hindered amine light stabilizer that is made from polymers. It has a low level of volatility, is resistant to migration, and can withstand high temperatures. When used in conjunction with UV absorbers and antioxidants, it has a remarkable synergistic effect.
Typical Physical Properties
Chemical Name:Poly{[(1,1,3,3-tetramethylbutyl )amino)-1,3,5-triazine-2,4-diyl}[2,2,6,6-tetramethyl
-4-piperidyl]imino]-1,6-hexanediyl[(2,2,6,-tetramethyl-4-piperidyl)imino]]}
Cas No.:70624-18-9
Appearance | White or light yellow solid |
Light transmittance | ≥93% （425nm） ≥95% （450nm） |
