Application |
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 has tribo gun effect for powder coating to increase powder static adhesive. |
