Product Description

Sipomer BEM (Ethoxylated Behenyl Methacrylate, CAS No. 125441-87-4) is a versatile long-chain hydrophobic methacrylate monomer engineered to enhance performance across a broad spectrum of polymer systems. Its ethoxylated C22 alkyl structure provides superior hydrophobicity, flexibility, anti-blocking, slip, and surface functionalization while ensuring excellent compatibility and copolymerization 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 robust chemical and thermal stability ensures consistent performance under industrial processing and high-demand applications.

Sipomer BEM improves film formation, water and chemical resistance, mechanical strength, pigment wetting, surface smoothness, and tactile feel, making it ideal for high-performance coatings, adhesives, inks, polymers, and functionalized materials. It can be used independently or synergistically with other monomers and additives to achieve customized polymer properties and advanced functional effects.
