Tinuvin® 5050 by BASF is a remarkable product with the following characteristics and features:

Composition and Blend:

It is a solvent-free, liquid blend of a 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) and a basic hindered amine light stabilizer (HALS). This unique combination brings together the advantages of both UV absorbers and light stabilizers, providing comprehensive protection against the harmful effects of ultraviolet light.

Performance Benefits:

Superior Coating Protection: The synergistic effect of the UVA and HALS in Tinuvin® 5050 imparts excellent protection to coatings. It effectively guards against various forms of degradation such as gloss reduction, cracking, blistering, delamination, and color change, ensuring the long-term stability and quality of the coated surface.

Broad UV Absorbance: The product has a broad UV absorbance spectrum, which makes it suitable for a wide range of coatings used on different substrates like wood, plastics, and metal. This broad-spectrum protection is crucial for materials that are exposed to a variety of UV wavelengths in different environments.

Substrate Protection: It provides full substrate protection, enhancing the durability and performance of the coated materials, and helping them to withstand the challenges of outdoor and industrial environments.

Applications:

Industrial Coatings: Widely used in exterior solventborne industrial coatings to meet the high cost/performance and durability requirements of these applications. It helps to protect industrial surfaces from UV damage, maintaining their appearance and functionality over time.

Furniture and Flooring Coatings: Ideal for coatings used on furniture and flooring, providing protection against UV-induced degradation and ensuring the longevity of the finish. It helps to maintain the color and gloss of the coated surfaces, even in high-traffic areas.

Digital Printing: Can be applied in digital printing to enhance the UV resistance of the printed materials, preventing fading and color changes caused by UV exposure. This is particularly important for printed products that are exposed to light for extended periods.

Physical Properties: It is a liquid product with certain physical properties that make it convenient for use in various coating formulations. The specific physical properties such as viscosity and solubility can be obtained from the technical datasheet provided by BASF.
