The performance and lifespan of modern coatings are significantly challenged by environmental factors, chief among them being ultraviolet (UV) radiation. UV exposure can lead to color fading, chalking, cracking, and overall degradation of the coating's protective and aesthetic properties. To combat this, formulators rely on advanced UV absorbers. One such crucial component that is gaining prominence is 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate, identified by its CAS number 96478-09-0.

As a dedicated manufacturer and supplier of fine chemicals in China, we recognize the importance of high-quality UV stabilization solutions for the coatings industry. This benzotriazole derivative offers a sophisticated approach to UV protection. Unlike traditional UV absorbers that are merely blended into a formulation, this methacrylate monomer possesses a reactive vinyl group. This means it can be chemically incorporated into the polymer network of the coating during the curing process. This covalent bonding ensures that the UV absorber remains permanently in place, providing enduring protection and preventing undesirable migration or leaching, which is a common drawback of many conventional additives.

The effectiveness of 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate stems from its molecular design. The benzotriazole core is highly efficient at absorbing UV light across a broad spectrum, particularly in the damaging UVA and UVB regions (typically 300-400 nm). Once the UV energy is absorbed, the molecule dissipates it harmlessly as heat through an intramolecular proton transfer mechanism. This rapid energy dissipation process is key to preventing the photochemical reactions that degrade polymers and pigments in coatings.

For purchasing managers in the coatings sector, understanding the benefits is crucial. When you buy this specialized monomer from a reputable China manufacturer, you're not just acquiring an ingredient; you're investing in enhanced product performance. Its physical form as a white to yellow crystalline powder (melting point 96-98°C) makes it compatible with many liquid resin systems and facilitates its inclusion in formulations for automotive finishes, architectural paints, industrial protective coatings, and even UV-curable inks.

The molecular formula C18H17N3O3 and molecular weight of 323.35 g/mol confirm its substantial chemical structure, designed for optimal interaction within coating matrices. Its ability to copolymerize means it integrates seamlessly into acrylic, polyurethane, and epoxy resin systems, improving their resistance to weathering and extending their service life. This is especially valuable for exterior applications where coatings are constantly bombarded by sunlight.

Moreover, its low potential for migration means that the protective properties are sustained over time, even under challenging environmental conditions. This translates to more durable, aesthetically pleasing, and functionally superior coatings. If your company is developing next-generation coatings that require superior UV resistance and longevity, procuring this advanced monomer is a strategic move.
