Butyl Acrylate

Butyl acrylate (CAS No. 141-32-2), or n-butyl acrylate, is a low-Tg acrylate monomer produced by the esterification of acrylic acid with n-butanol. This process yields a clear, colorless liquid noted for its pungent odor, with its chemical structure enabling a wide range of industrial applications. Butyl acrylate is often used in chemical manufacturing and polymerized with high-Tg monomers, such as methyl methacrylate, styrene, and vinyl acetate, to balance the properties of the final polymer, providing an optimal combination of attributes. By incorporating butyl acrylate into a polymer, manufacturers can significantly improve tack, flexibility, impact resistance, and overall durability. The flexibility and tack provided by butyl acrylate make it an ideal monomer for producing polymers used in adhesive and sealant formulas. Its ability to enhance impact resistance is crucial in applications demanding resilient materials, such as structural adhesives. Furthermore, butyl acrylate's compatibility with various other monomers facilitates its use in specialized formulations, thereby broadening its utility in the industrial landscape.
