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.

PRODUCT DETAIL
GC UV 161 PWB
It is our alternative of GC UV 326: this is a light stabilizer blend that shows excellent UV stabilization with minimal impact on color.
GC UV 326
2-(5-Chloro-2H-benzotriazol-2-yl)-6-(1,1-dimethylethyl)-4-methylphenol
CAS n. 3896-11-5
PHYSICAL FORM: GR, PW
It is suitable for polymers processed at high temperatures.
GC UV 571
A mixture of: isomers of 2-(2H-benzotriazol-2-yl)-4-methyl-(n)-dodecylphenol; isomers of 2-(2H benzotriazol-2-yl)-4-methyl-(n)-tetracosylphenol; isomers of 2-(2H-benzotriazol-2-yl)-4-methyl-5,6-didodecyl-phenol. n=5 or 6
PHYSICAL FORM: LIQ
It is an effective light stabilizer for a variety of polymers. It protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets and fibers during outdoor weathering. GC UV 571 can be used alone or in combination with other additives and it is liquid.
GC UV 1140
Reaction products of 2-(4,6-bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl)-5-hydroxyphenol with ((C10-16, rich in C12-13 alkyloxy)methyl)oxyrane
CAS N. 153519-44-9
PHYSICAL FORM: LIQ
It is an 85% solution of the active substance in 1-methoxy-2-propanol. GC UV 1140 is a liquid high efficient UV absorber mainly used as light stabilizing additive for high performance coatings.
GC UV 1130
A mixture of: α-3-(3-(2H-benzotriazol-2-yl)-5-tertbutyl-4-hydroxyphenyl)propionyl-ω-hydroxypoly (oxyethylene); α-3-(3-(2H-benzotriazol-2-yl)-5-tertbutyl- 4-hydroxyphenyl)propionyl-ω-3-(3 (2Hbenzotriazol-2-yl)-5-tert-butyl-4-hydroxyphenyl) propionyloxypoly (oxyethylene).
PHYSICAL FORM: LIQ
It is a liquid benzotriazole-based UV absorber for coating, printing and packaging, adhesives and sealants.
