Innovative & Multifunctional UV-Curable Material: 4-(Hydroxyvinyloxy)benzophenone Acrylate, CAS 22421-66-5

Responding to the trend toward higher efficiency, environmental friendliness and multifunctionality in the UV curing industry, our company proudly launches a new generation of reactive functional monomer — 4-(hydroxyvinyloxy)benzophenone acrylate (CAS 22421-66-5). As a breakthrough product integrating the triple functions of reactive diluent, Type II photoinitiator and UV absorber, this product features four core advantages: low migration, high reactivity, strong adhesion and excellent weather resistance. It completely revolutionizes traditional UV formulation systems and provides a more streamlined, efficient and stable integrated solution for high-end coatings, precision inks, electronic photoresists and adhesives.

I. Core Properties: Triple Functions in One, Superior Performance

Featuring a bifunctional molecular design combining benzophenone and acrylate groups, this product achieves multiple effects from a single material, greatly simplifying formulations, improving stability and outperforming traditional single‑function monomers and initiator combinations.

Triple Integrated Functions · Simplified and Efficient Formulation

Combining the roles of reactive diluent monomer, Type II photoinitiator and UV absorber, it enables efficient curing without additional photoinitiators, reduces formulation components, lowers costs and avoids compatibility issues caused by multiple additives.

Ultra-High Photoreactivity · Second-Level Curing

Synergistic action between acrylate double bonds and benzophenone photosensitive groups enables rapid polymerization initiation under UV irradiation, increasing curing speed by over 40%. It is compatible with high‑speed production lines, significantly improving productivity and reducing energy consumption.

Ultra-Low Migration · Food-Grade Environmental Compliance

With a stable molecular structure, it crosslinks tightly with the resin system after curing, resulting in extremely low residue and migration. It meets EU FDA and RoHS environmental standards and satisfies stringent safety requirements for food packaging and children’s products.

Strong Adhesion · Flexibility and Chemical Resistance

Excellent adhesion to plastics, metals, glass, paper and other substrates. The cured film combines high hardness and flexibility, with outstanding resistance to acids, alkalis, solvents, abrasion and boiling water, delivering comprehensively enhanced mechanical properties.

Long-Lasting Weather Resistance · Anti-Yellowing

Built-in UV absorption effectively blocks UV degradation. It exhibits no yellowing, chalking or gloss loss during long-term outdoor use, with weather resistance far exceeding conventional acrylate monomers.
