Dodecyl Methacrylate (commonly called Lauryl Methacrylate) CAS 142-90-5 is a long-chain alkyl methacrylate monomer used to impart hydrophobicity, flexibility and low surface energy to polymers and copolymers. Its lauryl side chain provides excellent water repellency, enhanced substrate wetting and improved flexibility in emulsion and solventborne coatings, pressure-sensitive adhesives and specialty polymers. When copolymerized with styrenics, acrylates or other methacrylates, it lowers the glass transition temperature and increases elongation while maintaining good UV and oxidative stability in cured systems.
