Introduction
Triethylene Glycol Divinyl Ether (DVE-3), a versatile difunctional monomer, is widely recognized for its exceptional solubility in epoxy resins and compatibility with cationic and free-radical systems. As the market demands eco-friendly and high-performance materials, U-Sunny Shenzhen's VM-3520 (DVE-3 equivalent) stands out as a premium solution for UV-curable coatings, adhesives, and composite formulations.
Technical Advantages of VM-3520
VM-3520 excels as a reactive diluent in epoxy-based systems due to its low viscosity (3 mPa·s at 25°C) and high purity (98.5%), ensuring seamless integration into resin matrices . Its dual functionality enhances crosslinking efficiency, reducing oxygen inhibition during LED/low-energy curing while improving film flexibility and pigment dispersion . Key properties include:
Flash Point: 119°C, ideal for industrial safety.
Boiling Point: 120–126°C @18 mmHg, minimizing VOC emissions.
Low Toxicity: A safer alternative to styrene-based diluents .
These attributes make VM-3520 indispensable for wood coatings, electronics encapsulation, and UV inks requiring rapid curing and durability.
