Sipomer BEM (Ethoxylated Behenyl Methacrylate, CAS No. 125441-87-4) is a high-performance long-chain methacrylate monomer designed to enhance the properties of a wide range of polymer systems. Its ethoxylated C22 alkyl structure delivers excellent hydrophobicity, flexibility, anti-blocking, slip, surface modification, and compatibility with acrylic, methacrylic, and other functional monomers.
Supplied at a purity of 49–52%, this clear to slightly hazy liquid is suitable for waterborne and solvent-based formulations, including emulsions, dispersions, solution polymers, and bulk polymerizations. Its chemical and thermal stability ensures reliable performance under demanding industrial conditions.
Sipomer BEM improves film formation, water and chemical resistance, mechanical durability, pigment wetting, surface smoothness, and tactile feel, making it ideal for manufacturers seeking versatile monomer solutions for high-performance coatings, adhesives, inks, and functional polymers. It can be used alone or blended with other monomers to achieve customized polymer properties and advanced functional materials.
