Tinuvin® 405 by BASF is a high-performance light stabilizer. Here is its detailed introduction:

Chemical Structure and Form: It is a solid triazine-based UV absorber. It appears as a light yellow powder.
 

Performance Features:

High Durability: Offers excellent durability, which is crucial for protecting coatings and plastics from the harmful effects of ultraviolet radiation. It can effectively prevent the degradation, fading, and embrittlement of materials caused by long-term UV exposure, thereby significantly extending the service life of the treated products.

Blue Shifted UV Absorption: It has a blue-shifted UV absorption characteristic, which means it can efficiently absorb ultraviolet light in a specific wavelength range. This property enables it to provide reliable protection in applications that require high UV resistance.

Good Compatibility: It shows good compatibility with various coating systems and polymer matrices, allowing for easy incorporation into different formulations without causing significant compatibility issues.
 

Application Areas:

Powder Coatings: Particularly suitable for acrylic powder coatings used in transportation and industrial applications. It helps to maintain the appearance and performance of the coatings in these demanding environments.

Other Coatings and Plastics: Can also be used in other types of coatings such as clear coats, as well as in various plastic products to enhance their UV resistance and overall durability.

Usage and Dosage: The appropriate dosage of Tinuvin® 405 depends on specific application requirements and the type of material being treated. Generally, it is added in a certain proportion to the coating or plastic formulation to achieve the desired UV protection effect. However, specific dosage recommendations should be determined through testing and experimentation.

In conclusion, Tinuvin® 405 is a valuable light stabilizer that provides reliable UV protection and durability enhancement for a wide range of coatings and plastic applications.
