SUNLIGHT® 123 is a hindered amine light stabilizer (HALS) of the amino ether type (equivalent to Tinuvin® 123) with excellent compatibility and low basicity, making it ideal for acid-catalyzed coating systems such as automotive OEM clearcoats. Its unique non-basic HALS structure prevents interference with acid-cure catalysts while delivering outstanding UV durability. SUNCHEM supports international buyers with SUNLIGHT® 123 sourcing from qualified Chinese producers, with quality documentation, export coordination, and logistics support.
