2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole: The Ultimate Solution for UV Protection

UV radiation is a major cause of deterioration and discoloration of polymers, plastics, and other organic materials. The consequences of UV damage include cracking, fading, and loss of mechanical strength, which can reduce the useful life of materials. To combat these effects, chemists and material scientists have developed a range of UV stabilizers that can be added to polymers to protect them from UV radiation. One such stabilizer is 2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole, also known as BASF light stabilizer Tinuvin 327, which is manufactured and supplied by INNO SPECIALTY CHEMICALS from China.

Chemical Properties

2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole is a white to yellowish crystalline powder that is insoluble in water but soluble in organic solvents. The molecular formula of the compound is C20H24ClN3O, and its molecular weight is 357.9 g/mol. The compound has a melting point of 155-160°C and a boiling point of 570°C. It is stable under normal conditions of use, storage, and transport.

Applications

2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole is a highly effective UV absorber that can be used in a wide range of polymers, including polyethylene, polypropylene, PVC, polycarbonate, polyester, acrylics, and styrene copolymers. It is particularly effective in protecting polymers from UV radiation in outdoor applications, such as automotive parts, construction materials, and outdoor furniture. The compound can also be used in adhesives, coatings, and inks to prevent UV-induced degradation and discoloration.

Benefits

2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole offers several benefits as a UV stabilizer. Firstly, it has a high degree of UV absorption, with a maximum absorption wavelength of 327 nm. This means that it can effectively protect materials from UV radiation in the range of 290-400 nm, which is the most damaging range for polymers. Secondly, it has a low volatility and migration rate, which means that it remains in the polymer matrix and does not leach out over time. This ensures long-term protection against UV radiation. Finally, it has a high thermal stability, which means that it can withstand high processing temperatures without degradation.

Safety

2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole is considered safe for use in polymers, coatings, and other applications. It is not classified as a hazardous substance under the EU CLP regulation or the US OSHA Hazard Communication Standard. However, as with all chemicals, it should be handled with care and stored in a cool, dry place away from heat and sources of ignition.

Conclusion

2-(3,5-Di-tert-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole is a highly effective and versatile UV stabilizer that offers a range of benefits for polymers, coatings, and other applications. Its high degree of UV absorption, low volatility, and thermal stability make it an ideal choice for protecting materials from UV damage.
