UV Absorber 400

Product Overview

UV Absorber 400 represents a significant advancement in the field of light stabilization technology, specifically engineered to meet the rigorous demands of modern coating systems. As a hydroxyphenyl-triazine derivative, this specialized chemical additive provides superior protection against ultraviolet radiation, ensuring the longevity and aesthetic integrity of finished products. Our manufacturing process guarantees high purity and consistency, making it an ideal choice for formulators seeking reliable performance in both waterborne and solventborne applications.

The unique molecular structure of this UV absorber allows for exceptional compatibility with a wide range of resin systems. Unlike traditional stabilizers, it offers low color characteristics which are critical for maintaining clarity in transparent finishes. This feature makes it particularly valuable for premium automotive clear coats and industrial finishes where visual appearance is paramount. The product is designed to work synergistically with other stabilizers, such as hindered amine light stabilizers, to provide comprehensive protection against weathering effects.

Technical Specifications

Quality control is central to our production methodology. Each batch undergoes rigorous testing to ensure compliance with international standards. The following table outlines the key physical and chemical characteristics that define the performance profile of UV Absorber 400.

These specifications ensure that the additive integrates seamlessly into formulations without compromising optical properties. The low volatility rating confirms thermal stability during processing, while the high transmittance values guarantee minimal interference with the desired color tone of the final coating.

Industrial Applications

This product is primarily utilized in high-performance coating systems where durability and weather resistance are critical. It is extensively used in the automotive industry for base coats and clear coats that require long-term gloss retention. Additionally, it serves as a key component in industrial finishes exposed to harsh environmental conditions, including direct sunlight and temperature fluctuations.

• Automotive OEM and refinish coatings
• Industrial protective finishes
• Waterborne and solventborne systems
• 100% solids coating formulations
• Combination with photoinitiators for UV cure systems

Formulators typically recommend a dosage range of 1% to 3%, depending on the specific resin system and the desired level of protection. When used in conjunction with compatible light stabilizers, it demonstrates a synergistic effect that significantly reduces gloss loss, cracking, bubbling, and discoloration over time.

Handling And Storage

To maintain optimal quality, containers should be kept tightly closed when not in use. The product must be stored in a cool, dry environment away from direct heat sources and moisture. Proper handling procedures ensure that the chemical properties remain stable throughout the shelf life. We provide comprehensive safety data sheets and certificates of analysis with every shipment to support regulatory compliance and quality assurance protocols.
