125441-87-4 Sipomer Bem Hydrophobic Methacrylate Monomer for Coatings, Adhesives, Inks, and Functional Polymers
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.
Applications
Industrial, decorative, and protective coatings
Waterborne and solvent-based adhesives, sealants, and pressure-sensitive adhesives
Emulsion, solution, and bulk polymerization systems
Printing inks, specialty coatings, and pigment dispersions
Functional polymer additives for hydrophobicity, slip, anti-blocking, and surface modification
Surface functionalization for plastics, composites, textiles, and leather
High-performance polymers and composites with enhanced durability, chemical resistance, and surface quality
Packaging
Available in IBC containers or 200 L drums, with custom packaging options available upon request.
