HALS 123 is a light stabilizer for PP, high dense PE, PU, PS, and ABS resin. It can work with antioxidants to improve heat resistance or work with UV Stabilizers to improve stability in light.

Tinuvin 123 is a low alkalescency light stabilizer, widely use in acrylic resins, polyurethanes, sealants, adhesives, rubber, blends of TPE and TPO, polyvinyl chloride, polystyrene, polypropylene and Other unsaturated resins. In addition, It will also cross-link with other ingredients in the coating formulation, so this product is especially recommended for coating. Excellent resistance to acids, flame retardants, sulfur and catalyst residues.

Storage & Package:

Sealed, keep in dry and ventilating place. packed in 25kg or 200kg plastic drum
