UV Absorber UV-400

Product Overview

UV Absorber UV-400 represents a significant advancement in light stabilization technology designed for demanding industrial environments. Identified by CAS number 153519-44-9, this high-efficiency hydroxyphenyltriazine liquid stabilizer offers exceptional protection against ultraviolet radiation. It is specifically engineered to maintain integrity under high bake conditions and extreme environmental exposure, making it a critical component for modern coating formulations. The hydroxyphenyltriazine structure provides a robust mechanism for absorbing harmful UV energy and dissipating it as harmless thermal energy. This molecular stability is key to preventing polymer degradation in the binder system.

Our manufacturing process ensures a high purity level, delivering consistent performance across diverse applications. The liquid physical state facilitates easy incorporation into various solvent systems, ensuring homogeneous distribution within the final product matrix. This product serves as a robust solution for manufacturers seeking to enhance the durability and aesthetic longevity of their surface coatings without compromising on clarity or processing efficiency.

Key Performance Features

• Exceptional thermal stability suitable for high-temperature curing processes.
• Non-interactive nature prevents interference with amine or metal catalysts.
• Low migration properties ensure long-term effectiveness within the coating layer.
• High transmittance values maintain clarity and color fidelity in clear coats.
• Synergistic effects when combined with hindered amine light stabilizers.

Technical Specifications

Industrial Applications

This specialized UV absorber is ideally suited for industrial paints and automotive coatings where high performance and durability are paramount. It is compatible with water-based, solvent-based, and 100% solids systems, providing versatility for formulators. Specific use cases include automotive OEM clear coats, coil coatings for building materials, and high-performance industrial finishes. The product excels in preventing common failure modes such as gloss loss, delamination, cracking, and blistering during the service life of the coating.

Particularly effective in amine-catalyzed or metal-catalyzed curing systems, UV-400 does not undergo cross-reactions with other system components. For optimal results, we recommend combining this absorber with UV-292 or UV-123 stabilizers. This combination creates a synergistic effect that significantly inhibits discoloration and surface degradation, ensuring the coated substrate retains its original appearance even after prolonged exposure to harsh weather conditions.

Storage and Packaging

To maintain product quality, UV Absorber UV-400 is packaged in 25kg plastic drums. The compound exhibits good storage stability under recommended conditions. Users should avoid exposure to high temperature and humidity during transportation and warehousing. It is advised to store the material in a cool, dry, and ventilated environment to prevent moisture absorption and heat accumulation, ensuring the chemical remains ready for immediate use in production lines.
