Tinuvin® 5251 by BASF is a high-performance light stabilizer product with the following features and characteristics:

Composition and Blend: It is a unique blend of different light stabilizer components, which may include hindered amine light stabilizers (HALS) and other additives. This carefully formulated blend provides a synergistic effect to offer enhanced protection against the harmful effects of ultraviolet (UV) light.

Performance Benefits:

Outstanding UV Resistance: Tinuvin® 5251 has excellent UV absorption and shielding capabilities. It can effectively prevent the degradation of materials caused by UV radiation, such as color fading, loss of mechanical properties, and cracking. This helps to extend the service life and maintain the quality of the treated materials.

Good Compatibility: It shows good compatibility with a wide range of polymers and resins, making it suitable for use in various polymer-based materials and coatings. This ensures that the light stabilizer can be evenly dispersed in the material matrix to provide consistent and reliable protection.

Thermal Stability: The product has high thermal stability, which means it can maintain its performance and effectiveness even under high-temperature processing or exposure conditions. This is particularly important for applications where the material is subjected to elevated temperatures during manufacturing or in use.

Applications:

Plastics Industry: It is widely used in the plastics industry to protect plastic products such as films, sheets, fibers, and molded parts from UV damage. It helps to maintain the appearance, mechanical properties, and durability of plastic products, especially those used in outdoor or high UV exposure environments.

Coatings and Paints: In the coatings and paints sector, Tinuvin® 5251 is added to formulations to enhance the UV resistance of the coatings, preventing color fading, chalking, and loss of gloss over time. It is suitable for both solvent-based and waterborne coating systems.

Adhesives and Sealants: It can also be used in adhesives and sealants to improve their UV stability and ensure the long-term performance of the bonded joints or sealed areas, especially in outdoor or UV-exposed applications.
