Description

Isophoryl Acrylate (CAS No. 86178-38-3) is a high-purity, monofunctional acrylate ester with the molecular formula C₁₂H₂₀O₂. This specialized monomer is widely used in UV-curable coatings, adhesives, and inks due to its excellent reactivity and low volatility. Its IUPAC name, (3,3,5-trimethylcyclohexyl) prop-2-enoate, reflects its unique cycloaliphatic structure, which contributes to enhanced hardness, chemical resistance, and weatherability in polymer formulations. Ideal for research and industrial applications, our Isophoryl Acrylate is rigorously tested for consistency, purity (>98%), and performance in free-radical polymerization systems. Available in amber glass bottles or bulk quantities with customizable packaging options.
