Imported anti-aging stabilizer HS-B19

Description Riquit® HS-B19 is a non-oligomeric high-molecular-weight hindered amine light stabilizer (HALS). It delivers remarkable improvement in the long-term light aging resistance of resins. HS-B19 also functions as an effective antioxidant; as a primary antioxidant, it can significantly enhance the long-term thermal stability of resins. Compared with conventional hindered amine light stabilizers, HS-B19 is a new third-generation HALS. It greatly reduces interactions with
