Sipomer BEM (Ethoxylated Behenyl Methacrylate, CAS No. 125441-87-4) is a versatile, high-performance long-chain methacrylate monomer engineered for a wide spectrum of polymer applications. Its unique ethoxylated C22 alkyl structure provides exceptional hydrophobicity, flexibility, anti-blocking, slip, and surface functionalization properties, while maintaining excellent copolymerization with acrylic, methacrylic, and other functional monomers.
Supplied at a purity of 49–52%, Sipomer BEM appears as a clear to slightly hazy liquid, fully compatible with both waterborne and solvent-based formulations, including emulsions, dispersions, and solution polymers. Its chemical and thermal stability ensures reliable performance under industrial processing conditions, making it ideal for high-performance coatings, adhesives, inks, and specialty polymers.
Sipomer BEM enhances film formation, surface smoothness, water repellency, chemical resistance, pigment dispersion, durability, and tactile feel, offering a versatile solution for manufacturers aiming to improve product performance across multiple industries. It can be used independently or in combination with other monomers and additives to achieve customized polymer properties and advanced functional materials.
