Product Overview

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.

Applications & Uses

  • UV stabilizer for automotive OEM clearcoat systems
  • Non-basic HALS for acid-cure coating applications
  • Light stability in industrial and architectural coatings
  • UV protection in two-component polyurethane coatings
  • Weathering resistance in automotive refinish coatings
  • Compatible HALS for acid-sensitive polymer systems
  • Polymer film and fiber UV stabilization
