Light Stabilizer UV-120: A Comprehensive Guide to Its Properties and Applications

UV radiation is known to cause damage to various materials, including polymers, plastics, and coatings. To counteract this effect, manufacturers use light stabilizers, which prevent discoloration, degradation, and other forms of damage caused by UV exposure. One such light stabilizer is Light Stabilizer UV-120, also known as BASF Tinuvin 120, UV Absorber UV-120, or Light Stabilizer 901.

Manufactured and supplied by INNO Specialty Chemicals in China, Light Stabilizer UV-120 is a popular choice for various industries, including automotive, construction, and packaging. In this article, we will explore the properties, benefits, and applications of Light Stabilizer UV-120.

Properties of Light Stabilizer UV-120

Light Stabilizer UV-120 is a type of hindered amine light stabilizer (HALS), which means that it prevents UV damage by scavenging free radicals and other reactive species. Specifically, it absorbs UV radiation in the range of 290-400 nm, which is the most damaging part of the spectrum.

The chemical structure of Light Stabilizer UV-120 consists of a benzotriazole moiety, which absorbs UV radiation, and a sterically hindered amine (HALS) moiety, which scavenges free radicals. This combination makes Light Stabilizer UV-120 highly effective in preventing UV damage to various materials.

In addition to its UV-absorbing and RAD-scavenging properties, Light Stabilizer UV-120 has other beneficial properties, such as low volatility, good compatibility with various resins and polymers, and high thermal stability. These properties make Light Stabilizer UV-120 suitable for use in various applications, such as coatings, adhesives, plastics, and elastomers.

Applications of Light Stabilizer UV-120

Light Stabilizer UV-120 is used in various industries and applications, such as:

Automotive: Light Stabilizer UV-120 is used in automotive coatings, such as clear coats and base coats, to prevent UV damage and maintain color and gloss retention. It is also used in automotive plastics, such as bumpers, dashboards, and interior trims, to prevent discoloration and degradation caused by UV exposure.

Construction: Light Stabilizer UV-120 is used in construction materials, such as paints, sealants, and adhesives, to prevent UV damage and maintain durability and weatherability. It is also used in roofing materials, such as membranes and coatings, to prevent degradation caused by UV exposure.

Packaging: Light Stabilizer UV-120 is used in packaging materials, such as films, bottles, and containers, to prevent discoloration and degradation caused by UV exposure. It is also used in food packaging materials, such as polyethylene and polypropylene, to prevent oxidation and maintain freshness.

Other applications: Light Stabilizer UV-120 is also used in other applications, such as electronics, textiles, and personal care products, to prevent UV damage and maintain performance and appearance.
