Adhesives and sealants are critical components in numerous industries, from automotive and construction to electronics and packaging. Their performance and durability are often challenged by environmental factors, with UV radiation being a significant contributor to premature failure. The incorporation of effective UV absorbers is essential to maintain the integrity and bond strength of these materials over time. UV Absorber 400, a high-performance triazine-based UV stabilizer, offers a robust solution for formulators seeking enhanced durability. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical manufacturer and supplier in China, provides this advanced additive to meet industry demands.

The Impact of UV on Adhesives and Sealants
When adhesives and sealants are exposed to UV light, the polymer matrix can undergo photo-oxidation. This process can lead to:

  • Loss of Adhesion: Weakening of the bond strength.
  • Cracking and Embrittlement: Reduced flexibility and physical integrity.
  • Discoloration: Unattractive yellowing or fading of the sealant.
  • Surface Degradation: Chalking and loss of sealing properties.

These issues can compromise the functionality of the bonded assembly, leading to costly failures. Therefore, protecting these critical interfaces from UV damage is paramount for ensuring long-term performance and reliability, especially in exterior applications.

UV Absorber 400: A Solution for Durable Adhesives
UV Absorber 400 (CAS 153519-44-9) is a liquid hydroxyphenyl-triazine (HPT) UV absorber that provides excellent UV protection, making it highly suitable for adhesive and sealant formulations. Its key benefits include:

  • Broad-Spectrum UV Absorption: Effectively blocks harmful UV radiation (290-400 nm), preventing photo-degradation of the adhesive matrix.
  • High Thermal Stability: Ensures that the stabilizer remains effective even during high-temperature curing or application processes.
  • Low Volatility: Minimizes loss during manufacturing and use, providing sustained protection throughout the product's lifespan.
  • Good Compatibility: Can be integrated into various adhesive chemistries and systems, including solvent-based, water-based, and 100% solids formulations.
  • Enhanced Durability: When used in conjunction with Hindered Amine Light Stabilizers (HALS), it offers synergistic protection, significantly improving weatherability and extending the service life of the adhesive bond.
