3-(Acryloxy)propyltrimethoxysilane CAS 4369-14-6

1. 3-(Acryloxy)propyltrimethoxysilane CAS 4369-14-6 is primarily used as a dual-functional coupling agent and adhesion promoter, where the acrylate group undergoes free-radical polymerization with organic resins and the silane group bonds to inorganic surfaces (e.g., glass, metals, fillers).
2. 3-(Acryloxy)propyltrimethoxysilane serves as a surface modifier for silica, glass fibers, and minerals in composite materials to enhance interfacial bonding, moisture resistance, and mechanical performance.
3. 3-(Acryloxy)propyltrimethoxysilane functions as a cross-linking agent and reactive monomer in UV-curable or radiation-curable coatings, inks, adhesives, and dental restorative materials.

1. Store 3-(acryloxy)propyltrimethoxysilane CAS 4369-14-6 in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed containers under an inert atmosphere with appropriate polymerization inhibitors (e.g., hydroquinone, MEHQ).
2. Keep 3-(acryloxy)propyltrimethoxysilane away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents, peroxides, and free radical initiators to avoid hazardous polymerization or exothermic reactions.
3. Handle 3-(acryloxy)propyltrimethoxysilane using non-sparking tools and grounded equipment; ensure containers are clearly labeled and kept sealed to prevent moisture absorption and premature condensation.

1. Immediately evacuate and isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; absorb leaking liquid with inert, non-combustible materials to prevent spread.
2. Collect spilled 3-(acryloxy)propyltrimethoxysilane and contaminated absorbents into sealable, chemical-resistant containers for disposal as polymerizable hazardous waste.
3. Clean the contaminated surface thoroughly with an appropriate solvent or detergent; collect all cleanup materials and dispose of them in full compliance with local, national, and international regulations for flammable and reactive hazardous waste.

1. 3-(Acryloxy)propyltrimethoxysilane CAS 4369-14-6 is flammable and may cause severe skin burns, eye damage, and respiratory irritation upon contact or inhalation of vapors/mists.
2. 3-(Acryloxy)propyltrimethoxysilane is a skin and respiratory sensitizer; repeated or prolonged exposure can lead to allergic reactions, including dermatitis and asthma.
3. Always handle 3-(acryloxy)propyltrimethoxysilane in a well-ventilated area or fume hood, wearing appropriate PPE including chemical-resistant gloves, protective clothing, face shield, and suitable respiratory protection.
