What is Diethylene glycol diacrylate?
Diethylene glycol diacrylate (CAS 4074-88-8), also referred to commercially as oxydiethylene diacrylate, is a bifunctional acrylate monomer used as a reactive crosslinker and diluent in UV- and peroxide-curable systems.
Where is Diethylene glycol diacrylate used?
- UV-curable coatings and inks: reactive diluent
- Printing and packaging: fast-curing flexographic and screen inks
- Adhesives and sealants: builds cohesive strength by tying polymer chains into tighter networks during cure
- Polymer manufacturing: crosslinking comonomer in acrylic resins and hydrogel matrices
- Its dual acrylate functionality enables rapid network formation, giving formulators control over cure speed, crosslink density, and final film hardness.
Good to know: Typically inhibited with hydroquinone monomethyl ether to prevent premature polymerization during storage and transport.
Commercial specifications
- Purity specifications commonly at 98% or higher
- Packaging ranges from drums to IBC totes depending on order volume
