2-Octyl cyanoacrylate
2-Octyl cyanoacrylate, identified by CAS 133978-15-1, is a high-performance cyanoacrylate ester characterized by an eight-carbon alkyl chain. As a liquid monomer, it exhibits unique physical properties compared to shorter-chain analogs, such as methyl or ethyl cyanoacrylates. The extended octyl chain contributes to a polymerized structure that is notably more flexible and resilient, offering improved impact resistance and lower brittleness in finished applications.
In industrial and research settings, this material is valued for its rapid anionic polymerization when exposed to moisture or basic surfaces. It functions as a versatile chemical intermediate and a specialty adhesive base. Due to its specific molecular weight and vapor pressure, it often demonstrates lower volatility and reduced odor during handling, making it a preferred choice in environments where user comfort and precise application are prioritized.
• Used as a primary component in the formulation of high-flexibility adhesives. The long alkyl chain allows the resulting polymer to withstand mechanical stress and thermal expansion better than standard cyanoacrylates, making it suitable for bonding dissimilar substrates like plastics, elastomers, and metals in dynamic environments.
• Serves as a specialty coating material in industrial processes where moisture-resistant barriers are required. Its ability to form a strong, hydrophobic film upon polymerization provides protection for sensitive components against environmental degradation, moisture ingress, and chemical exposure.
• Utilized in research and development for the synthesis of advanced polymers and copolymers. Researchers leverage the unique reactivity of the cyanoacrylate group alongside the steric properties of the octyl side chain to create tailored materials with specific glass transition temperatures and mechanical profiles.
• Employed in the production of high-viscosity bonding agents for vertical or porous surfaces. Because the curing rate can be controlled through stabilization, it allows for more precise positioning of parts in assembly lines before the final bond is established, reducing waste and improving manufacturing efficiency.
