Light Stabilizing Agent 622

Butanedioic acid polymer with(4-hydroxy-2,2,6,6-tetramethyl-1-piperidineethanol). It acts as a light stabilizer. It is an oligomer with good process heat stability and has good compatibility with resin. It is water-fast and is effective to prevent the degradation of high polymer caused by light, heat and weather, water. It is white or light yellow grain sol-name. It is used in polyethylene, polypropylene, polystyrene, olefin co-polymer and polyester, soft PVC.
