Description

2-(2-Hydroxyethoxy)Ethyl Acrylate is a bifunctional monomer featuring both a polymerizable acrylate group and a hydroxyl-terminated polyether chain. This unique structure makes it a versatile chemical intermediate for creating polymers with enhanced flexibility, adhesion, and hydrophilicity. It is primarily sought after by formulators and manufacturers in the coatings, adhesives, and specialty polymer industries who require tailored performance characteristics in their final products.

Application

• UV-Curable Coatings and Inks: As a reactive diluent and crosslinker to improve film flexibility, adhesion to substrates, and cure speed.
• Acrylic Resin Modification: To introduce hydrophilic polyether segments, enhancing water dispersibility and impact resistance in emulsion polymers.
• Pressure-Sensitive Adhesives (PSAs): Used in the synthesis of acrylic copolymers to balance tack, peel strength, and cohesion.
• Hydrogel and Contact Lens Materials: Imparts hydrophilicity and oxygen permeability in the production of soft, biocompatible polymers.
• Fiber Optic Coatings: Contributes to the synthesis of protective primary coatings with the necessary flexibility and low modulus.
• Photopolymer Resins for 3D Printing: Serves as a key component in stereolithography (SLA) and digital light processing (DLP) resins to modify viscosity and mechanical properties.

Quality Control

Our 2-(2-Hydroxyethoxy)Ethyl Acrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets exacting industry standards for performance and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, and we support compliance with relevant global regulatory frameworks.

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 polymerizable and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and use appropriate inhibitors as supplied. Keep away from heat, sparks, and open flame.
