Coatings play a vital role in protecting surfaces and enhancing their aesthetic appeal, but their performance can be significantly compromised by exposure to ultraviolet (UV) radiation. UV-induced degradation can lead to chalking, fading, cracking, and loss of gloss, diminishing both the protective function and the visual quality of coated materials. For manufacturers of paints and coatings, incorporating effective UV protection is not just a matter of aesthetics, but also of ensuring long-term durability and customer satisfaction. This is where high-performance UV absorbers, such as UV Absorber UV-328, become indispensable.

UV Absorber UV-328 (CAS: 25973-55-1) is a superior UV absorbent with a strong absorption capacity in the UV-A and UV-B regions, particularly at its peak absorption wavelength of 345nm. Its excellent compatibility with a wide array of resins commonly used in coatings, including polyesters, epoxies, and cellulose resins, makes it a versatile additive. Furthermore, its low volatility ensures that it remains within the coating film during curing and service life, providing continuous protection. The high wash resistance of UV-328 means that the protective properties are maintained even when the coated surface is cleaned or exposed to solvents.

As a leading manufacturer and supplier of specialty chemicals, we understand the demands of the coatings industry. UV Absorber UV-328 is highly recommended for use in various coating systems, contributing to enhanced light stability and overall performance. Typically, a dosage of around 1% is sufficient to achieve significant protection, though specific amounts may be optimized based on the coating formulation and intended application. For outdoor applications, UV-328 can be effectively combined with other stabilizers, such as hindered amine light stabilizers (HALS) and antioxidants, to create a synergistic protective system that maximizes the lifespan and appearance of the coating.

When considering the purchase of UV Absorber UV-328, it is crucial to partner with a reputable supplier who guarantees high purity (≥99%) and consistent quality. Our commitment to excellence ensures that you receive a product that meets stringent performance standards. We offer competitive pricing for bulk orders, making it a cost-effective solution for enhancing your coating formulations. Whether you are formulating automotive coatings, industrial finishes, or wood coatings, UV Absorber UV-328 is a valuable additive that can significantly improve your product's resilience against UV damage.
