  Application
  LIGHT STABILIZER LS-144 is a light stabilizer of the hindered amine class (HALS) and also contains an antioxidant moiety of the sterically hindered phenol type. Its efficiency provides significantly extended life time to coatings by minimizing paint defects such as cracking and loss of gloss. It is recommended for applications including automotive coatings, coil coatings, and powder coatings. The performance of 144 can be significantly improved when used in combination with a UV absorber like UV1130, UV928 etc.
