Tiangang® HS-508 is a highly effective radical scavenger belonging to the Hindered Amine Light Stabilizers (HALS) family of stabilizers. It is a liquid HALS that displays outstanding light stabilities in applications, like coatings, printing ink, and polyurethane lacquer, preventing the surface from blowing-out or peeling-off. It is widely used for light stability in polypropylene, polyethylene, styrenics, unsaturated polyester, acrylics, vinyl polymers (PVC, PVB), including plastisols, elastomers, adhesives, sealants and coatings. In particular, it is often recommended for polyurethanes because of its solubility in polyols. Tiangang® HS-508 (292) typically demonstrates reduced interaction with co-additives such as pigments or other stabilizers. Tiangang® HS-508 (292) has strong synergy effect with UV absorbent of benzotriazo family, particularly when used in coatings for automotives and wooden furniture.
