Top 10 Categories of UV Light Absorbers
A UV absorber is a type of light stabilizer capable of absorbing the ultraviolet (UV) portion of sunlight and fluorescent light sources without undergoing any chemical change itself.
Since sunlight contains a significant amount of UV radiation—with wavelengths ranging approximately from 290 to 460 nanometers—that is harmful to colored objects, this damaging UV light triggers chemical redox reactions that ultimately cause color molecules to decompose and fade.
Physical vs. Chemical Methods
Methods for preventing the destructive effects of harmful UV light on colors can be broadly classified into two categories: physical methods and chemical methods.
This section focuses solely on the chemical approach—specifically, the use...
