Isobornyl acrylate

CAS: 5888-33-5

Overview

Isobornyl acrylate (CAS 5888-33-5 ), commonly abbreviated as IBOA, is a reactive monomer used in UV-curable and radiation-curable polymer systems. It functions as a diluent monomer that reduces viscosity in resin formulations.

This monomer contributes hardness, chemical resistance, and low shrinkage to the cured film. It is a primary building block in UV-curable coatings, inks, and adhesives, where it controls flow properties during application.

In printing and packaging, it is incorporated into energy-curable inkjet and flexographic ink formulations. These applications help achieve fast cure speeds and durable print surfaces for various industrial substrates.

Personal care formulators use this chemical in nail gel systems and UV-curable film-forming products. It is preferred where rigid, glossy finishes are required for high-end cosmetic and professional applications.

It also appears in optical adhesives and lens coatings due to its low volatility. Its compatibility with acrylate oligomers supports precision bonding applications in the electronics and optics industries.

The product is supplied as a clear to pale yellow liquid. Standard commercial grades are available at high purity levels, typically 98% or higher, to meet industrial manufacturing requirements.

The material includes inhibitor packages suited for storage and handling in monomer supply chains. It is commonly offered in drum and IBC quantities with bulk availability from major distributors.
