1,3-Butanediol diacrylate, identified by CAS number 19485-03-1, is a bifunctional monomer widely utilized in radiation-curable systems due to its efficient reactive properties. As a clear, low-viscosity liquid, it functions effectively as a reactive diluent, facilitating the adjustment of formulation viscosity without compromising the final performance of the cured material. Its chemical structure, featuring two acrylate functional groups, allows it to participate in rapid polymerization processes, contributing to the formation of highly crosslinked networks.
In industrial and research settings, this compound is valued for its balance of reactivity and flexibility. It exhibits low volatility and a high flash point, which enhances its handling profile compared to more volatile monomers. The resulting polymers typically demonstrate excellent weatherability, chemical resistance, and adhesion to various substrates. Because it is sensitive to light and heat, proper storage with polymerization inhibitors is essential to maintain stability during transport and long-term use.
