CAS: 73936-91-1

Benzotriazole UV Absorber

Description

UV-928 is a solid benzotriazole-based UV absorber for coatings, printing and packaging, adhesives and sealants.

Chemical name:

2-(2H-Benzotriazol-2-yl)-6-(1-methyl-1-phenylethyl)-4-(1,1,3,3-tetramethylbutyl)phenol

Molecular formula:

C29H35N3O

Molecular weight:

441 g/mol

CAS number:

73936-91-1

EC number:

422-600-5

Applications

UV-928 significantly improves the resistance of automotive OEM and industrial high-temperature baking coatings, powder coatings, overprint varnishes over metal, board, paper, laminates, adhesives and sealants. For outdoor applications, UV-928 needs to be combined with a hindered amine light stabilizer (HALS) such as LS-123 (for acid-catalyzed systems) or LS-292 (for 2K PUR).
