01. What Exactly is DVE-3 (VM-3520)?
Triethylene Glycol Divinyl Ether (DVE-3) has the chemical formula C₁₀H₁₈O₄, molecular weight of 202.25, and CAS number 765-12-8. It is a colorless to pale yellow transparent liquid with a density of 0.99 g/mL (25°C) and boiling point between 120-126°C.
Chemically, DVE-3 contains two vinyl ether functional groups, giving it bifunctional reactivity characteristics.
02. The Exceptional Properties and Advantages of DVE-3 (VM-3520)
Outstanding Dilution Capability
DVE-3 has an extremely low viscosity of only 2.64 mPa·s at 25°C, making it an efficient reactive diluent in UV curing systems. It significantly reduces the viscosity of resin systems, improves processability, while maintaining performance after curing.
Dual Curing Mechanisms
One of the most notable features of DVE-3 is its compatibility with both free radical and cationic systems. This characteristic makes it an ideal choice for dual-cure (hybrid) systems, providing greater flexibility for formulation designers.
Excellent Curing Performance
In cationic photocurring systems, DVE-3 demonstrates extremely fast curing speed, low shrinkage, and high double bond conversion rate. This means fewer residual monomers, more environmentally friendly cured products, and more stable final performance.
Enhanced Adhesion and Flexibility
The ether bonds in DVE-3's molecular structure help enhance adhesion between coatings and substrates, while providing good flexibility and bend resistance to the cured film.
03. Main Application Fields of DVE-3 (VM-3520)
UV Curing Coatings and Inks
DVE-3 is widely used in UV curing coatings and inks, particularly suitable for applications requiring high adhesion and smoothness. Its rapid curing characteristics in cationic systems make it a key component in producing high-performance UV coatings.
UV Inkjet Printing
In the UV inkjet field, DVE-3's low viscosity and high reactivity make it an ideal diluting monomer. It ensures smooth operation of printheads while enabling instant curing after jetting, significantly improving production efficiency.
Adhesives and Sealants
When used in UV curing adhesives, DVE-3 provides excellent bonding performance and cohesive strength. Its high double bond conversion rate ensures low migration and good aging resistance after adhesive curing.
3D Printing Photosensitive Resins
In the field of liquid photocurring resin 3D printing, DVE-3 serves as a key component that effectively adjusts resin viscosity, increases curing speed, and significantly reduces shrinkage. This directly translates to higher printing accuracy and better dimensional stability.
Other Specialized Applications
DVE-3 can also be used as a crosslinking agent for polyacrylate ion exchange resins in hydrogel preparation, and as a reactive modifier in other unsaturated polyester systems.
