Tinuvin® 5070 by BASF is a high-performance light stabilizer product with the following characteristics and features:

Composition and Blend:

It is a unique blend that combines a 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) and a hindered amine light stabilizer (HALS). This combination brings together the advantages of both components, providing comprehensive and synergistic protection against the harmful effects of ultraviolet (UV) light.

Performance Benefits:

Superior UV Protection: Tinuvin® 5070 offers excellent UV absorption and stabilization properties. It effectively absorbs UV radiation and dissipates the energy as heat, preventing the degradation of the polymer or coating caused by UV exposure. This helps to maintain the integrity of the material, reducing the risk of fading, cracking, and other forms of deterioration over time.

Long-Term Durability: The product provides long-lasting protection, ensuring the stability and performance of the treated material even under prolonged exposure to sunlight and other environmental factors. This makes it suitable for applications where durability is a key requirement, such as in outdoor coatings, plastics, and synthetic materials.

Compatibility and Processability: It has good compatibility with a wide range of polymers and coating formulations, allowing for easy incorporation into the production process. It does not interfere with the processing characteristics of the material, ensuring smooth manufacturing and application.

Applications:

Coatings and Paints: Widely used in various coating systems, including architectural coatings, industrial coatings, and automotive coatings. It helps to enhance the UV resistance of the coatings, maintaining their color, gloss, and mechanical properties over a long period.

Plastics and Polymers: Effective in protecting plastic materials such as polyethylene, polypropylene, polyvinyl chloride, and engineering plastics from UV-induced degradation. It can be added during the manufacturing process of plastics to improve their outdoor durability and lifespan.

Adhesives and Sealants: Also finds application in adhesives and sealants to improve their UV resistance, ensuring the bonding strength and integrity of the adhesive joints even in outdoor or UV-exposed environments.

Technical Specifications: The specific technical specifications of Tinuvin® 5070, such as its chemical structure, molecular weight, and physical properties (such as solubility, melting point, etc.), can be obtained from the technical data sheet provided by BASF. These specifications are important for formulators and users to understand the product's behavior and performance in different applications.
