Description

Polyethyleneglycol Diacrylate is a bifunctional monomer featuring two reactive acrylate groups linked by a flexible poly(ethylene glycol) chain. This unique structure makes it a versatile crosslinking agent and building block for creating hydrophilic, flexible polymer networks. It is essential for formulators and manufacturers in industries requiring materials with specific mechanical properties and water affinity. The compound is widely utilized in advanced applications ranging from specialty coatings to biomedical hydrogels.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker in formulations for wood, plastic, and metal coatings, providing excellent flexibility and adhesion.
• Photopolymer Resins for 3D Printing: A key component in stereolithography (SLA) and digital light processing (DLP) resins, contributing to low shrinkage and tunable mechanical properties in printed parts.
• Hydrogel Synthesis for Biomedical Uses: Used to create crosslinked hydrogels for drug delivery systems, wound dressings, and tissue engineering scaffolds due to its biocompatibility and hydrophilicity.
• Adhesives & Sealants: Imparts toughness and durability to acrylic-based adhesive formulations, enhancing performance in demanding industrial applications.
• Fiber Optic Coatings: Employed in the production of primary and secondary coatings for optical fibers, offering protection and signal integrity.
• Dental Composites & Restoratives: Functions as a crosslinking monomer in light-curable dental materials, improving strength and wear resistance.

Quality Control

Our Polyethyleneglycol Diacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC, determination of acid value, and measurement of color and water content, to ensure it meets precise specifications for purity and performance. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and incompatible materials such as strong oxidizers and bases. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
