Triethylene glycol divinyl ether

Triethylene glycol divinyl ether (CAS 765-12-8), also marketed as Rapi-Cure DVE-3, is a difunctional vinyl ether monomer used as a reactive diluent and crosslinker in UV-curable and radiation-curable systems.

Where is Triethylene glycol divinyl ether used?

• UV-curable inks and coatings: viscosity reduction for high-speed printing
• Adhesives: crosslink density tuning, balancing peel strength and elongation in pressure-sensitive and structural systems
• Sealants and elastomers: improved substrate wetting and compliance in cured formulations
• It improves cure speed and flexibility in the final film.

Good to know: Unlike inert solvents, it reduces formulation viscosity while contributing to the cured network rather than being driven off during processing. Its flexible glycol backbone makes it effective as a reactive plasticizer where brittleness must be controlled without sacrificing cure performance.
