125441-87-4 Sipomer BemEthoxylated Behenyl Methacrylate Monomer for Coatings, Adhesives, Inks
Product Description
Sipomer BEM (Ethoxylated Behenyl Methacrylate, CAS No. 125441-87-4) is a versatile long-chain hydrophobic methacrylate monomer designed to enhance performance in a wide range of polymer systems. Its unique ethoxylated C22 alkyl structure provides exceptional flexibility, hydrophobicity, anti-blocking, slip, and surface-modifying properties while maintaining excellent copolymerization with acrylic, methacrylic, and other functional monomers.
This monomer is supplied at a purity of 49–52% and appears as a clear to slightly hazy liquid. It is compatible with both waterborne and solvent-based systems, including emulsions, dispersions, and bulk polymerizations. Its chemical and thermal stability ensure consistent performance under industrial processing conditions.
Sipomer BEM is widely used across multiple applications to improve film softness, water repellency, chemical resistance, mechanical durability, pigment wetting, and surface properties. It can be used independently or in combination with other monomers and additives to optimize polymer properties for tailored performance.
Applications
Industrial coatings, paints, and varnishes
Adhesives, sealants, and pressure-sensitive adhesives
Emulsion and solution polymerization systems
Inks, printing coatings, and specialty polymers
Surface modification agents and functional polymer additives
Textile and leather finishes
Plastics and composite materials with improved hydrophobicity and surface slip
Packaging
Standard packaging includes IBC containers or 200 L drums. Custom packaging options can be provided according to client requirements.
