Description

2-Acryloyloxyethyl 2-Hydroxyethyl Phthalate is a specialized bifunctional monomer featuring both acrylate and phthalate ester groups within its molecular structure. This compound is valued for its ability to act as a reactive diluent and crosslinking agent, imparting tailored properties such as flexibility, adhesion, and durability to polymer matrices. It is primarily sought by formulators and manufacturers in the photopolymer, UV-curable resin, specialty adhesive, and advanced coating industries for developing high-performance materials.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker to enhance cure speed, film flexibility, and chemical resistance.
• Photopolymer Resins: A key monomer for stereolithography (SLA) and other 3D printing resins, contributing to part toughness and resolution.
• Adhesives & Sealants: Used in acrylic-based formulations to improve adhesion to diverse substrates and adjust viscosity.
• Dental & Medical Polymers: Employed in the synthesis of biocompatible polymers for restorative materials and medical devices.
• Optical Fiber Coatings: Imparts necessary protective and mechanical properties to the secondary coating layers.
• Electronics Encapsulation: Used in potting compounds and encapsulants that require specific dielectric and mechanical properties.

Quality Control

Our 2-Acryloyloxyethyl 2-Hydroxyethyl Phthalate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure high purity, consistent performance, and compliance with agreed specifications. A detailed Certificate of Analysis (COA) providing results for assay, identity, and impurity profiles is supplied with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). This material is light-sensitive and easily oxidized; prolonged exposure to light, heat, or air should be avoided to maintain stability and prevent premature polymerization. For long-term storage, consider an inert atmosphere (e.g., nitrogen blanket).
