Product Description:
Stearyl Methacrylate is a long-chain alkyl methacrylate monomer used to impart hydrophobicity, flexibility, and improved processability to polymer systems. Known for its excellent slip, lubricity, and water-repellent properties, Stearyl Methacrylate is widely used in coatings, plastics, adhesives, and specialty polymers where surface feel and moisture resistance are key. Its long hydrocarbon chain provides low surface energy, making it ideal for anti-blocking, release, and weather-resistant applications.
