1,3-Butanediol diacrylate
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.
• In the formulation of UV and electron beam (EB) curable coatings, 1,3-butanediol diacrylate serves as a critical crosslinking agent. It enhances the mechanical strength and surface hardness of the finished film while maintaining a degree of flexibility that prevents brittleness, making it suitable for wood, plastic, and metal finishes.
• The monomer is extensively used in the production of high-performance inks and varnishes, specifically for lithographic and flexographic printing. Its low viscosity allows for high pigment loading and improved flow characteristics, while its fast curing speed supports high-speed printing processes with superior solvent resistance.
• Within the adhesives and sealants industry, this diacrylate acts as a reactive component to improve bonding strength and thermal stability. It is frequently incorporated into structural adhesives to tailor the crosslink density, ensuring that the adhesive maintains its integrity under environmental stress and mechanical load.
• Beyond traditional coatings, it finds application in the synthesis of specialty polymers used in electronics and 3D printing. Its ability to form dense, three-dimensional networks through free-radical polymerization makes it an ideal building block for photoresists and photopolymer resins where precise structural control is required.
