TINUVIN® 123

TINUVIN 123 is a liquid hindered amine light stabilizer (HALS) based on an amino-ether functionality. It has been developed especially for high solids, acid catalyzed automotive and industrial coatings, such as two-coat metallic thermosetting acrylate systems or one-coat opaque thermosetting acrylate and polyester coatings. Its low basicity prevents possible interactions with acidic paint ingredients such as catalysts. Its efficiency provides significant improvement in coatings performance by minimizing paint defects such as cracking and gloss reduction for clear coats as well as chalking for pigmented paints.

Product highlights

  • Efficient protection against gloss loss and cracking of coatings
  • Low basicity aminoether (NOR) HALS, permits formulating in acid catalyzed coatings and coatings containing acidic pigmentation
  • Low volatility
