Tinuvin® 400



TINUVIN® 400 is a liquid hydroxyphenyl-triazine (HPT) UV absorber designed to fulfill the high performance and durability needs of waterborne, solvent borne, and 100% solids automotive and industrial finishes. Its low color and stability make it an excellent choice for all coatings where low color characteristics are ideal for use in combination with the newest generation photoinitiators to provide durable UV clear coats.


  • Excellent long-term performance (photo permanence)
  • Reactable via OH function into NCO- and melamine-cross linked systems
  • Non-migrating
  • Does not interact with amine- and/or metal-catalyzed coating systems or coatings applied on base coats or substrates containing such catalysts
  • Low color, low migration
  • Minimal interaction with metal catalysts and amine crosslinkers
  • High thermal stability
  • Hydroxyphenyl-triazine with high absorbance in the UV-B region
