Siwin-LS770
Light stabilizer
The Light Stabilizer 770 is a type of hindered amine light stabilizer that has a low molecular weight. It is resistant to migration and has a high temperature tolerance, with the added benefit of low volatility. This product works well with other UV absorbers and antioxidants, creating a synergetic effect that improves the anti-aging properties of materials.
