  • Applications

    Stearyl methacrylate is used primarily as a hydrophobic alkyl methacrylate monomer in polymer formulations for coatings and inks, contributing hardness, high gloss, and chemical resistance; it also serves as a comonomer in UV- and radical-cured coatings and adhesives to improve film formation and water resistance; in the plastics and polymers sector it helps impart waxy, low-surface-energy characteristics to specialty polymers and molded parts; in cosmetics and personal care it may act as a film-forming polymer modifier or wax-like ingredient to adjust texture and appearance; and in electronics-related coatings it supports protective, transparent layers for components and displays due to its hydrophobicity and compatibility with UV-curing systems.
