Description

2-(4-Benzoyl-3-Hydroxyphenoxy)Ethyl Acrylate is a specialized bifunctional monomer featuring both a photoreactive benzophenone moiety and a polymerizable acrylate group. This unique molecular structure makes it a critical photo-crosslinking agent and reactive diluent in advanced polymer formulations. It is essential for manufacturers in the photopolymer, specialty coatings, and advanced adhesive industries seeking to enhance material properties through UV-initiated curing mechanisms.

Application

• UV-Curable Coatings & Inks: Serves as a key reactive diluent and crosslinker to improve hardness, chemical resistance, and cure speed.
• Photopolymer Resins: Used in stereolithography (SLA) and other 3D printing resins to control viscosity and final material properties.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to introduce photo-crosslinking capability, enhancing shear strength and thermal resistance.
• Optical Fiber Coatings: Imparts durability and specific refractive index properties in protective cladding materials.
• Electronic Encapsulants: Utilized in formulations for potting and protecting electronic components where fast, low-temperature curing is required.
• Dental & Biomedical Composites: Acts as a co-monomer in light-curable composites for restorative and prosthetic applications.

Quality Control

Our production of 2-(4-Benzoyl-3-Hydroxyphenoxy)Ethyl Acrylate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and assay, GC for residual monomer and solvent content, and IR for structural identification. We provide Certificates of Analysis (COA) with each shipment, ensuring traceability and compliance with your technical requirements and internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
