Tinuvin® 5248 is a liquid light stabilizer blend incorporating a triazine-based UV absorber and a basic hindered amine light stabilizer (HALS) for coatings, adhesives, and sealants. Formulated to address the high performance and durability needs of exterior solvent-based automotive, industrial, architectural, and decorative coatings, including energy-curable systems (UV, electron beam). Key features and benefits include high thermal stability and photo permanence, containing a basic multipurpose HALS, a UV absorber insensitive to metal ions and amines, preventing the formation of colored complexes, and a synergistic combination providing superior coating protection against gloss reduction, cracking, blistering, delamination, or color change, ensuring comprehensive substrate protection.
