125441-87-4 Sipomer Bem Ethoxylated Behenyl Methacrylate Monomer for Coatings, and Surface Functionalization
Product Description
Sipomer BEM (Ethoxylated Behenyl Methacrylate, CAS No. 125441-87-4) is a high-performance, long-chain hydrophobic methacrylate monomer designed to enhance the properties of a wide range of polymer systems. Its unique ethoxylated C22 alkyl structure delivers superior flexibility, water repellency, anti-blocking, slip, and surface-modifying properties while ensuring excellent copolymerization with acrylate, methacrylate, and other functional monomers.
Supplied at a purity of 49–52%, Sipomer BEM appears as a clear to slightly hazy liquid and is fully compatible with waterborne and solvent-based formulations. Its robust chemical and thermal stability ensures consistent performance under industrial processing conditions, making it ideal for high-performance and specialty polymer applications.
Sipomer BEM is widely utilized to improve film formation, durability, hydrophobicity, chemical resistance, pigment wetting, and surface finish, offering versatile solutions for coatings, adhesives, inks, polymers, and surface-functional materials. It can be incorporated independently or synergistically with other monomers and additives to achieve tailored performance in a variety of formulations.
Applications
Industrial and decorative coatings, paints, and varnishes
Waterborne and solvent-based adhesives, sealants, and pressure-sensitive adhesives
