Description

Dicyclopentenyloxyethyl acrylate (CAS No. 65983-31-5) is a high-purity specialty acrylate monomer with the molecular formula C₁₅H₂₀O₃. This compound, also known by its IUPAC name 2-(8-tricyclo[5.2.1.0^2,6]dec-3-enyloxy)ethyl prop-2-enoate, features a unique dicyclopentenyloxyethyl group that enhances reactivity and cross-linking capabilities in polymer systems. It is a clear, colorless to pale yellow liquid with a characteristic acrylic ester odor, designed for advanced applications in UV-curable coatings, adhesives, and photopolymer resins. Its low volatility and high boiling point make it ideal for formulations requiring controlled curing kinetics. Packaged under inert gas to prevent premature polymerization, this monomer is rigorously tested for purity, stability, and performance consistency. Suitable for research and industrial use, it is compatible with free-radical initiators and photoinitiators for tailored polymerization processes.

Application

Dicyclopentenyloxyethyl acrylate is widely used as a reactive diluent and cross-linking agent in UV-curable coatings, inks, and adhesives due to its excellent film-forming properties and fast cure rates. Its unique structure enhances adhesion to low-energy substrates like plastics and metals, making it valuable in automotive and electronic coatings. The monomer is also employed in photopolymer resins for 3D printing and dental composites, where its high reactivity and low shrinkage are critical.
