  Application
  LIGHT STABILIZER HOSORB-622 acts as a hindered amine light stabilizer. It shows low volatility and minimal migration due to high molecular weight and it also has antioxidant properties. It is widely used in polyolefin (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomer. It is highly effective in polyacetal, polyamide and polyurethane. It is also used in adhesive, sealant, fiber and film. It can be combined with other HALS or UV absorbers to attain synergistic effects.
