UV-1577
Low Volatile Hydroxyphenyl Triazine UV Absorber
Description
UV-1577 is an ultraviolet light absorber (UVA) of the hydroxyphenyl triazine class exhibiting very low volatility and good compatibility with a variety of polymers, co-additives and resin compositions. UV-1577 allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers.
Chemical name:
2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-((hexyl)oxy)phenol
Molecular formula:
C27H27N3O2
Molecular weight:
425 g/mol
CAS number:
147315-50-2
EC number:
411-380-6
Applications
UV-1577 applications include polyalkene terephthalates and naphthalates, linear and branched polycarbonates, modified polyphenylene ether compounds, and various high-performance plastics.
The use of UV-1577 is indicated in polymer blends & alloys, such as PC/ABS, PC/PBT, PPE/IPS, PPE/PA and copolymers as well as in reinforced, filled and/or flame retarded compounds, which can be transparent, translucent and/or pigmented. Its very low tendency to chelate allows UV-1577 formulations in polymers containing catalyst residues.
