CAS 10311-7: 2-Ethylhexyl Acrylate Properties & Industrial Uses

The chemical properties of CAS 103117 (2-ethylhexyl acrylate, 2EHA) determine its reactivity, stability, and suitability for polymerization, making them foundational to its use in adhesives, coatings, and resins. 2EHA is an ester with the formula C11H20O2, containing a reactive acrylic double bond (C=C) that undergoes free radical polymerization, enabling copolymerization with monomers like methyl acrylate, styrene, or acrylic acid to form versatile polymers. It is relatively stable under normal conditions but can polymerize spontaneously in the presence of heat, light, or initiators, which is why inhibitors (e.g., MEHQ) are added to prevent premature polymerization during storage. 2EHA is resistant to hydrolysis under neutral conditions but may degrade in strong acids or bases, releasing acrylic acid and 2-ethylhexanol. It is flammable, with a lower explosive limit (LEL) of ~1% and upper explosive limit (UEL) of ~8% in air, requiring precautions against ignition. As a non-polar compound, it exhibits good compatibility with organic solvents and hydrophobic polymers, enhancing its role in water-resistant formulations. E Plus Chemical Co., Ltd.’s 99% pure CAS 103117 2EHA maintains these chemical properties consistently, ensuring reliable polymerization behavior and contributing to the performance of end products like flexible adhesives and weather-resistant coatings.
