2-Ethylhexyl acrylate (2EHA) with CAS 103117 is a fundamental monomer in adhesive formulations, particularly in water-based pressure-sensitive adhesives (PSAs), where it enhances critical properties such as tack, peel strength, and flexibility. Its chemical structure, characterized by a reactive acrylate group (CH2=CH-COO-) and a branched 2-ethylhexyl chain, enables efficient copolymerization with other monomers like methyl acrylate, acrylic acid, or vinyl acetate. This copolymerization forms polymers that balance adhesion (the ability to stick to surfaces) and cohesion (internal strength), which are essential for reliable adhesive performance. The 2-ethylhexyl chain contributes to a low glass transition temperature (Tg) in the resulting polymer, ensuring the adhesive remains pliable across a wide temperature range, from sub-zero conditions in cold storage to elevated temperatures in automotive or industrial settings. This flexibility prevents the adhesive from becoming brittle or losing tack under extreme temperatures. Additionally, the hydrophobic nature of the 2-ethylhexyl chain improves the adhesive’s resistance to moisture, making it suitable for applications in humid environments, such as packaging for refrigerated goods or outdoor labels. For medical adhesives, the high purity (99%) of 2EHA with CAS 103117, as produced by E Plus Chemical Co., Ltd. using advanced catalytic polymerization technology, minimizes impurities that could cause skin irritation, ensuring compatibility with sensitive skin in products like medical tapes and transdermal patches. E Plus Chemical’s 50,000-ton annual production capacity ensures a stable supply of this high-purity 2EHA, supporting large-scale adhesive manufacturing with consistent quality. By adjusting the proportion of 2EHA in copolymer formulations, manufacturers can tailor adhesives for specific needs: higher 2EHA content enhances flexibility and tack for conformable tapes, while lower content improves shear strength for industrial bonding applications. This versatility makes 2EHA with CAS 103117 an indispensable component in the adhesives industry, driving innovation in both consumer and industrial adhesive products.
