125441-87-4 Sipomer Bem Hydrophobic Surface-Modification Methacrylate Monomer, 49–52% Purity

Product Description

Sipomer BEM (Ethoxylated Behenyl Methacrylate, CAS No. 125441-87-4) is a high-performance long-chain methacrylate monomer widely used to enhance the functionality of advanced polymer systems. With a purity of 49–52%, it provides excellent hydrophobicity, surface slip, flexibility, anti-blocking effects, and durable surface modification, making it a valuable component in both waterborne and solvent-based formulations.

Its ethoxylated C22 structure offers strong compatibility with acrylic and methacrylic monomers, enabling stable copolymerization in emulsion, solution, and bulk polymerization processes. Sipomer BEM is particularly effective in improving film integrity, chemical resistance, water repellency, mechanical durability, pigment dispersion, and surface smoothness. These properties make it ideal for manufacturers seeking enhanced performance in high-quality coatings, adhesives, inks, and specialty polymer materials.

Sipomer BEM is commonly applied in decorative and industrial coatings, pressure-sensitive adhesives, sealants, printing inks, plastic and textile surface treatments, and functional additives for high-performance polymer formulations. Its stability under heat and chemical exposure ensures consistent performance in demanding industrial environments.
