| Hazard Information | Back Directory | [Physical properties]
It is white to faint yellow powder. The specific gravity is 1.07 at 25℃. It is easy soluble in toluene, chloroform, hexane, soluble in acetone etc. | [Uses]
The product belongs to the class of hindered hydroxybenzoate light stabilizer. UV-2908 is most suitable for the protection of polyolefins, polycarbonate and the systems containing flame retardants and thioesters. It can be used alone or in combination with benzophenone UV stabilizer or phosphite antioxidant, showing good synergistic effect.The dosage of UV-2908 ranges between 0.25% and 1% are recommended for protection. It depends on the substrate and performance requirement of the final application. | [benefits]
Low volatility, minimal color contribution, good chemical stability, acid and alkali resistant, excellent compatibilty with UV absorbers, HALS, and thioesters, FDA sanctioned to 0.5% in polyolefins | [Flammability and Explosibility]
Notclassified | [Safety]
In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. Use only with adequate ventilation. Avoid dust formation and ignition sources | [Synthesis]
1.Add 3,5-di-tert-butyl-4-hydroxybenzoic acid (3.03 g), 1-hexadecanol (4.42 g), toluene (30 ml) and dried ion-exchange resin (1.49 g, 20 wt%) into a two-necked round flask equipped with a magnetic stirrer for 11.5 hours.2.High performance liquid chromatography is adopted to monitor the reaction and determine the component of the reaction mixture. |
