UV Absorbers
The product portfolio proposed by B.A. Special Chem & Color includes a complete range of UV-Absorbers:
Uses and classifications
To protect organic substrates from harmful UV radiation and the resulting photo-oxidation that causes degradation of the material, it is essential to use the appropriate light stabilizer.
UV Absorbers filter UV light, preventing colour changes in the polymer, resin, substrate and pigments or dyes included in the recipe of paints and coatings, inks, adhesives and sealants.

UV absorbers can be divided up according to the type of chemical:
● Hydroxy benzophenones
● Hydroxyphenyl benzotriazoles
● Hydroxyphenyl triazines
● Oxanilides
● Formamidines
● Hydroxyphenyl benzotriazoles
● Hydroxyphenyl triazines
● Oxanilides
● Formamidines
There are also various blends of UV Absorbers, specifically designed for certain applications.
