Molecular formula: C29H42O3

CAS NO: 4221-80-1

Chemical name:

3,5-di-tert-butyl-4-hydroxybenzoic acid-2,4-di-tert-butylphenyl ester

Characteristics and uses:

Light stabilizer UV120 is a benzoate light stabilizer, which has the dual functions of light stabilizer and antioxidant. It can absorb UVB and UVC, with an absorption peak of 265 nanometers. It has the characteristics of high temperature resistance, extraction resistance, low volatility, and low migration. It is suitable for PC, PET, PBT, PMMA, coatings, and inks. It is used in combination with high molecular weight light stabilizers and ultraviolet absorbers, and the synergistic effect is significant.
