3-(Trimethoxysilyl)propyl methacrylate  (Synonyms: [3-(Methacryloyloxy)propyl]trimethoxysilane)

3-(Trimethoxysilyl)propyl methacrylate ([3-(Methacryloyloxy)propyl]trimethoxysilane) is a reactive monomer and silane coupling agent with C=C and O-C=O functional groups, acting as a surface modifier and anti-agglomeration agent. 3-(Trimethoxysilyl)propyl methacrylate can be used to prepare nanoparticles^[1][2].

3-(Trimethoxysilyl)propyl methacrylate (1-20% by mass relative to TiO₂; 60 min hydrolysis, 120 min modification stirring, 30 min high-speed stirring, 4 h Soxhlet extraction, 4 h vacuum drying) successfully grafts to rutile TiO₂ nanoparticles, with maximum grafting efficiency of 97.7% at the 3% (0.15 mL per 5 g TiO₂) concentration; modification reduces particle agglomeration, increases surface hydrophobicity to a contact angle of 111.76°, and leaves the TiO₂ rutile crystal structure and individual particle size/shape unchanged^[2].

*In solvent : -80°C, 6 months; -20°C, 1 month (stored under nitrogen)

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
