UV Absorbers
UV absorbers act by absorbing the UV radiation and dissipating the resulting energy in a non-
photosensitizing way, such as heat, by intramolecular proton transfer.

DESCRIPTION
PRODUCT DETAIL
GC UV-1
Ethyl 4-[[(methylphenylamino)methylene]amino]benzoate
CAS n. 57834-33-0
PHYSICAL FORM: LIQ

It is an UV absorber mainly used as light stabilizing additive for polymers to prevent discolouring or yellowing.
GC CHIM 81
Octabenzophenone
CAS n. 1843-05-6
PHYSICAL FORM: PW, FLAKES

It is a light stabilizer recommended for applications that demand low volatility and minimal migration.
GC UV 3050
2,2’,4,4’-Tetrahydroxybenzophenone
CAS n. 131-55-5
PHYSICAL FORM: PW

UV absorber very suitable for applications in which an optimum filter effect up to the boundary with visible light is desired.
GC UV 3049
2,2-Dihydroxy-4,4-dimethoxy benzophenone
CAS n. 131-54-4
PHYSICAL FORM: PW

It is an efficient UV absorber for polyester film, which it protects from premature damage, particularly under severe exposure conditions.
