Description

Thiol Diethylene Glycol Diacrylate is a specialized bifunctional monomer containing both thiol and acrylate groups within a diethylene glycol backbone. This unique structure makes it a highly effective crosslinking agent and reactive diluent for applications requiring precise control over polymer network formation and properties. It is essential for formulators and polymer chemists in industries demanding advanced material performance. Key markets include UV-curable coatings, advanced adhesives, and specialty polymer synthesis.

Application

• UV-Curable Coatings and Inks: Acts as a reactive diluent and crosslinker to enhance cure speed, adhesion, and chemical resistance in formulations for electronics, automotive, and industrial finishes.
• Thiol-Ene Polymerization Systems: Serves as a key monomer in click chemistry applications, enabling the synthesis of polymers with low shrinkage, uniform networks, and tailored mechanical properties.
• Adhesive and Sealant Formulations: Used to improve flexibility, toughness, and environmental stability in high-performance structural and pressure-sensitive adhesives.
• Dental and Biomedical Materials: Employed in the development of biocompatible resins and composites due to its efficient polymerization and potential for creating controlled-release matrices.
• Optical Fiber and Lens Coatings: Provides excellent clarity and durability in protective coatings for sensitive optical components.
• 3D Printing Resins (SLA/DLP): Enhances resolution, mechanical strength, and post-cure properties in photopolymer resins for additive manufacturing.
• Modifier for Rubber and Elastomers: Used to introduce crosslinks and improve the thermal and aging resistance of synthetic rubbers.

Quality Control

Our Thiol Diethylene Glycol Diacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC, purity verification, and control of critical impurities like residual monomers and peroxides, to ensure consistent performance and reliability for your formulations. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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). Keep away from heat, sparks, and open flame. Due to the presence of acrylate and thiol functional groups, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize potential polymerization or oxidation.
