Chemical Name: 2-(2'-Hydroxy-3',5'-di-t-amylphenyl)benzotriazole
Molecular Formula:C22H29N3O
Molecular Weight: 351
CAS No.:25973-55-1
Properties
Benzotriazole ultraviolet absorbent
often used with hindered amine light stabilizers to improve the resistance of paint loss of light, pulverization, bubbles, delamination, color performance, more recommendation application in room temperature and low temperature curing coatings system.
Application
It is a versatile, efficient, and heat-resistant ultraviolet light absorber. It serves as a key additive for protecting organic materials such as plastics, coatings, and adhesives from solar aging, thereby extending their outdoor service life.
Storage
Keep container tightly closed in a cool, well-ventilated place.
The recommended max. storage life is 12 month when stored under normal conditions.
