The Benefits and Applications of INNO Specialty Chemicals' 3,5-Di-tert-butyl-4-hydroxybenzoic acid-2,4-di-tert-butylphenyl ester (Tinuvin 120)

INNO Specialty Chemicals is a leading manufacturer and supplier of specialty chemicals in China. One of their most popular products is the 3,5-Di-tert-butyl-4-hydroxybenzoic acid-2,4-di-tert-butylphenyl ester, also known as Tinuvin 120 or UV-120. This chemical compound is widely used as a UV absorber and light stabilizer in various applications, from plastics and coatings to adhesives and textiles.

UV-120 is a type of hindered amine light stabilizer (HALS) that helps prevent the degradation of materials caused by exposure to UV radiation. It works by absorbing UV light and converting it into harmless heat energy, thus reducing the damage to the underlying material. This makes it an essential ingredient in many products that are exposed to sunlight or other sources of UV radiation, such as outdoor furniture, automotive parts, and electronic devices.

One of the key advantages of UV-120 is its high efficiency in absorbing UV light. It has a strong absorption peak at around 325 nm, which is in the range of the most harmful UV radiation. This means that even in small concentrations, UV-120 can provide excellent protection against UV-induced degradation. It also has a broad absorption spectrum, which allows it to cover a wider range of wavelengths than other UV absorbers.

Another benefit of UV-120 is its compatibility with various polymer systems. It can be used in a wide range of plastics, including polyethylene, polypropylene, polystyrene, PVC, and ABS. It is also compatible with many coatings, adhesives, and other materials. This makes it a versatile additive that can be used in many different applications.

UV-120 is also highly stable and resistant to migration. It does not react with other ingredients in the material, nor does it migrate to the surface or leach out over time. This ensures that the protective effect of UV-120 remains consistent over the lifespan of the material.

Some of the common applications of UV-120 include:

1. Plastics: UV-120 is widely used in the production of plastic products that are exposed to sunlight, such as outdoor furniture, garden hoses, and automotive parts. It helps prevent the degradation of the plastic and extends its lifespan.

2. Coatings: UV-120 is often added to coatings and paints to protect the underlying surface from UV radiation. It is used in coatings for buildings, bridges, and other outdoor structures.

3. Adhesives: UV-120 is used in adhesives and sealants to prevent the degradation of the bond caused by UV radiation. It is used in automotive, construction, and aerospace applications.

4. Textiles: UV-120 is added to textiles and fabrics to prevent fading and degradation caused by exposure to sunlight. It is used in outdoor clothing, awnings, and other UV-sensitive textiles.

In conclusion, INNO Specialty Chemicals' 3,5-Di-tert-butyl-4-hydroxybenzoic acid-2,4-di-tert-butylphenyl ester (Tinuvin 120) is a highly effective UV absorber and light stabilizer that offers many benefits in various applications. Its high efficiency, compatibility, stability, and resistance to migration make it a versatile and reliable additive for protecting materials from UV-induced degradation.
