Tinuvin® 249 by BASF is a remarkable light stabilizer with the following characteristics:

Chemical Nature:

It is a liquid non-basic hindered amine light stabilizer (HALS) specifically designed for solvent-based coatings.

This chemical composition enables it to effectively capture free radicals and protect coatings from the harmful effects of light.

Physical Properties:

Physical Form: Liquid, which offers ease of handling and incorporation into coating formulations.

Viscosity: It has relatively low viscosity, facilitating its dispersion in various solvents and coating systems.

Color: It has a very low inherent color, minimizing the impact on the color of the final coating.

Molecular Weight: 482 g/mol.
 

Performance Features:

High Durability: Meets the high-performance and durability requirements of all solvent-based automotive, industrial, and decorative coatings where other HALS may fail due to basicity or compatibility issues.

Thermal Stability: Exhibits high thermal stability, ensuring its effectiveness even at elevated temperatures during the coating process and in the final cured coating.

Compatibility: Shows broad compatibility in solvent-based systems of different polarities, allowing it to be used in a wide range of coating formulations without causing compatibility problems.

Color Stability: Helps maintain excellent color stability during the shelf life of the coating, preventing color fading or changes over time.

Application Areas:

Widely used in the automotive industry for OEM (original equipment manufacturer) and refinish coatings.

Applied in industrial coatings, such as those used for machinery, equipment, and metal structures.

Used in furniture and floor coatings to enhance their resistance to light and improve their durability.

Suitable for other applications where high-performance light stabilization is required, such as in optical coatings and certain plastic coatings.
