The automotive industry demands coatings that not only look stunning but also withstand the harsh realities of everyday exposure to sunlight, weather, and environmental pollutants. Ultraviolet (UV) radiation is a primary culprit in the degradation of automotive finishes, leading to fading, chalking, and a loss of gloss. To combat this, high-performance UV absorbers are indispensable, and UV Absorber 928 has emerged as a cornerstone additive in this sector.

UV Absorber 928, with its chemical structure and properties, offers a robust defense against UV-induced degradation in automotive coatings. Its ability to absorb a wide range of UV wavelengths ensures that critical components of the paint system, including the binder and pigments, are shielded from damaging radiation. This protection is vital for maintaining the vibrant colors and high-gloss finish that consumers expect from their vehicles.

The application of UV Absorber 928 in automotive coatings is multifaceted. It is incorporated into clear coats to protect the underlying base coat and pigments from fading and delamination. Its excellent thermal stability is also advantageous, as automotive finishes are often subjected to elevated temperatures during manufacturing processes and, of course, during use in hot climates or under direct sunlight. Furthermore, its low volatility means that it remains integrated within the coating film, providing durable protection that lasts for the vehicle's lifetime.

Beyond aesthetics, UV protection is crucial for the structural integrity of automotive coatings. UV degradation can compromise the coating's adhesion to the substrate, leading to blistering and peeling. By effectively absorbing UV light, UV Absorber 928 helps to preserve the mechanical properties of the coating, ensuring it remains intact and protective.

The effectiveness of UV Absorber 928 can be further enhanced when formulated with Hindered Amine Light Stabilizers (HALS). This combination provides a synergistic effect, where the UV absorber blocks incoming UV light, and the HALS neutralize any free radicals that might still form. This dual protection is a standard practice in high-quality automotive paint systems to ensure maximum durability and resistance to weathering. NINGBO INNO PHARMCHEM CO.,LTD. is proud to provide high-quality UV Absorber 928, enabling automotive paint manufacturers to achieve superior product performance and customer satisfaction.
