UV Absorber 928

Product Overview

UV Absorber 928 represents a significant advancement in the field of hydroxyphenyl benzotriazole light stabilizers, engineered specifically to meet the rigorous demands of high-performance coating applications. This sophisticated chemical additive functions by absorbing harmful ultraviolet radiation and dissipating it as harmless thermal energy, thereby preventing photodegradation of the underlying polymer matrix. Its unique molecular structure, defined by the chemical name 2-(benzotriazol-2-yl)-6-(2-phenylpropan-2-yl)-4-(2,4,4-trimethylpentan-2-yl)phenol, ensures exceptional compatibility with a wide range of resin systems.

As a premium specialty chemical, UV Absorber 928 is synthesized to deliver superior longevity and aesthetic preservation for materials exposed to harsh environmental conditions. The product is characterized by its light yellow crystalline powder appearance and high purity levels, making it a reliable choice for manufacturers who prioritize quality and consistency in their final formulations. Our commitment to excellence ensures that every batch meets strict international standards for chemical performance and safety.

Key Specifications

Industrial Applications

The broad-band absorption capabilities of UV Absorber 928 provide efficient protection to coatings and light-sensitive substrates, making it indispensable in industries where durability is paramount. It exhibits excellent solubility and high thermal stability, which makes it particularly suitable for coatings exposed to high-temperature curing processes. This includes demanding sectors such as automotive finishes, where long-term gloss retention and color stability are critical metrics of success.

Recommended applications extend to powder coatings and coil coatings, where the additive must withstand extreme processing conditions without decomposing or volatilizing. The typical use levels range between 1 and 3 percent, depending on the specific requirements of the formulation and the desired level of protection. For outdoor applications subject to intense weathering, UV Absorber 928 can be effectively used in combination with Hindered Amine Light Stabilizers (HALS) to optimize performance and extend the service life of the coated material significantly.

Handling And Storage

To maintain the integrity and efficacy of UV Absorber 928, proper handling and storage protocols must be observed. The product should be kept in tightly closed containers to prevent moisture absorption and contamination. Storage areas must be cool, dry, and well-ventilated, away from direct sunlight and sources of ignition.
