3-Methacryloxypropylmethyldimethoxysilane CAS 14513-34-9

1. 3-Methacryloxypropylmethyldimethoxysilane is primarily used as a bifunctional silane coupling agent to improve adhesion between organic polymers (such as polyethylene, polystyrene, ABS, and unsaturated polyester) and inorganic materials (such as glass, metals, and silica) .
2. 3-Methacryloxypropylmethyldimethoxysilane CAS 14513-34-9 serves as a building block to impart methacryloxy functional groups into new polymers and as a surface modifier for fillers and reinforcements, significantly enhancing the mechanical strength, electrical properties, and wet-state performance of composite materials .
3. 3-Methacryloxypropylmethyldimethoxysilane is employed in the formulation of coatings, adhesives, and sealants, where its methacryloxy group enables covalent bonding with polymer matrices while the methoxysilyl groups react with inorganic substrates .
4. Researchers utilize 3-Methacryloxypropylmethyldimethoxysilane CAS 14513-34-9 in material science for fiberglass treatment, in the production of reinforced plastics, and for improving the compatibility and durability of polymer composites across various industrial applications including automotive and construction sectors .

1. 3-Methacryloxypropylmethyldimethoxysilane must be stored in a tightly sealed container under inert atmosphere (nitrogen or argon) in a cool, dry, and well-ventilated environment at 2-8°C, protected from moisture as it is moisture sensitive and may undergo hydrolysis and polymerization .
2. 3-Methacryloxypropylmethyldimethoxysilane CAS 14513-34-9 is classified with GHS hazard statements including H315 (Causes skin irritation), H319 (Causes serious eye irritation), H227 (Combustible liquid), and H410 (Very toxic to aquatic life with long-lasting effects), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves (nitrile rubber), tightly fitting safety goggles with side-shields, face protection, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and avoiding formation of dust and aerosols .
4. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents; prevent release to the environment (P273); note that the compound may polymerize if exposed to heat, light, or polymerization initiators like peroxides .

1. Isolate the spill area, ensure adequate ventilation, remove all sources of ignition, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and appropriate respiratory protection when 3-Methacryloxypropylmethyldimethoxysilane is released .
2. Collect 3-Methacryloxypropylmethyldimethoxysilane CAS 14513-34-9 using non-sparking tools by absorbing with inert materials such as sand, diatomite, or universal binders, and place into suitable closed containers for disposal; use spark-proof and explosion-proof equipment .
3. Avoid creating vapors or mists during cleanup to prevent respiratory exposure; decontaminate surfaces using appropriate methods; prevent the product from entering drains or water courses as it is very toxic to aquatic life with long-lasting effects (P391) .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration with flue gas scrubbing (P501) .

1. 3-Methacryloxypropylmethyldimethoxysilane is a combustible liquid with a flash point ranging from 44°C to 109°C depending on test method (NFPA fire rating 2), requiring moderate heating before ignition; under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, silicon oxides, and acrid smoke .
2. Use 3-Methacryloxypropylmethyldimethoxysilane CAS 14513-34-9 dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use water jet as it may scatter burning material and react with moisture .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 3-Methacryloxypropylmethyldimethoxysilane due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination and pollution .
