Formulation chemists constantly seek to enhance the performance and longevity of their coatings. A key challenge, particularly for automotive and industrial finishes, is protecting them from the damaging effects of ultraviolet (UV) radiation. This is where advanced UV absorbers, such as the triazine derivative UV Absorber 400, become indispensable. From our position as a leading specialty chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD., we aim to provide formulators with the high-quality materials needed to achieve superior results.

The Crucial Role of UV Protection in Coatings
Coatings are the first line of defense for substrates against environmental factors, including UV light. Without adequate protection, coatings can suffer from gloss reduction, chalking, cracking, delamination, and color change. This not only compromises the aesthetic appeal but also the protective function of the coating, leading to premature failure and increased maintenance costs. The demand for durable, high-performance coatings, especially in automotive OEM and refinish applications, necessitates the use of effective UV stabilization packages.

Introducing UV Absorber 400: A Superior Solution
UV Absorber 400 (CAS 153519-44-9) is a liquid hydroxyphenyl-triazine (HPT) UV absorber engineered for exceptional performance in coatings. Its key attributes make it a preferred choice for formulators:

  • Broad UV Absorption: It effectively absorbs UV radiation in the 290-400 nm range, providing comprehensive protection.
  • Excellent Thermal Stability: This allows for incorporation into coatings that undergo high-temperature curing processes without degradation.
  • Low Color and Low Volatility: It imparts minimal color to the formulation and resists migration, ensuring long-term effectiveness and clarity.
  • Compatibility with Catalyzed Systems: Specifically designed to work without adverse interactions in amine or metal-catalyzed coating systems, making it ideal for modern formulations.
  • Synergistic Effects with HALS: When combined with Hindered Amine Light Stabilizers (HALS), such as HALS 123 or HALS 292, UV Absorber 400 significantly boosts overall weatherability, protecting against gloss reduction and physical degradation.

Formulation Considerations and Sourcing from China
When incorporating UV Absorber 400 into your formulations, typical usage levels range from 1.0% to 3.0% (based on binder solids), often in combination with 0.5% to 2.0% HALS for optimal results. Its liquid form facilitates easy dispersion and handling in both solvent-borne and waterborne systems, as well as 100% solids formulations.
