In the competitive landscape of chemical manufacturing and material science, understanding the precise properties and applications of key additives is crucial for product development and differentiation. UV Absorber 928 (CAS: 73936-91-1) stands out as a high-performance UV absorber, widely recognized for its effectiveness in protecting sensitive materials from the damaging effects of ultraviolet radiation. As a leading manufacturer and supplier in China, we are dedicated to providing comprehensive information to help our clients leverage the full potential of this essential chemical.

UV Absorber 928 is characterized by its light yellow crystalline powder appearance. Chemically, it is a benzotriazole derivative with a molecular formula of C29H35N3O and a molecular weight of approximately 441.61. Its standout features include a broad absorption spectrum, high solubility, excellent thermal stability, and low volatility. These attributes make it exceptionally suitable for a variety of demanding applications where UV protection is critical. For instance, it is frequently used in high-performance coatings, including automotive finishes, powder coatings, and coil continuous coatings. Its ability to withstand high-temperature curing processes without significant degradation is a key advantage. Professionals looking to buy UV absorber 928 should prioritize these technical specifications.

The mechanism by which UV Absorber 928 functions is through the absorption of UV light and its subsequent dissipation as thermal energy. This prevents the UV radiation from initiating photochemical reactions within the polymer or coating that lead to material breakdown. For manufacturers of plastics, paints, and adhesives, this translates into extended product lifespan, preserved aesthetic qualities, and maintained mechanical integrity. Furthermore, when UV Absorber 928 is used in combination with Hindered Amine Light Stabilizers (HALS), such as UV-292 or UV-123, its protective performance is significantly enhanced, offering a more robust defense against photodegradation. This synergy makes it a highly sought-after component when looking for a reliable UV absorber 928 supplier.

Procurement professionals and R&D scientists often seek competitive pricing without compromising on quality. We understand this need and strive to offer a compelling UV absorber 928 price, reflecting both the premium quality of our product and our efficient manufacturing processes. As a dedicated UV absorber 928 CAS 73936-91-1 manufacturer, we ensure that each batch meets stringent purity standards, typically ≥98.5% by HPLC, and exhibits consistent physical properties such as a melting point of 108-112°C and high transmittance at 460nm and 500nm.

In conclusion, UV Absorber 928 is an indispensable additive for any formulation that requires superior protection against UV radiation. Its proven efficacy in coatings and plastics, coupled with its excellent thermal and chemical stability, makes it a valuable investment for enhancing product durability.
