Triethoxypropylsilane CAS 2550-02-9

1. Triethoxypropylsilane CAS 2550-02-9 is primarily used as a silane coupling agent to improve adhesion between organic polymers (e.g., plastics, rubbers) and inorganic substrates such as glass, metals, and mineral fillers like silica and talc .
2. Triethoxypropylsilane serves as a key precursor in sol-gel processes for synthesizing organic-inorganic hybrid materials, enabling the creation of coatings and networks with tailored optical, electrical, and mechanical properties .
3. In industrial applications, Triethoxypropylsilane is employed as a surface modifier to impart hydrophobicity and water resistance to materials like glass fibers, inorganic fillers, flame retardants, stone, and cement-based products, and also acts as a crosslinker for room-temperature-vulcanized silicone rubber .
4. Researchers utilize this product as an electron donor in polypropylene polymerization with Ziegler-Natta catalysts, and in the fabrication of OLEDs as an interface modification material to optimize anode work function and improve hole injection efficiency .

1. Triethoxypropylsilane CAS 2550-02-9 must be stored in a tightly sealed container under inert atmosphere (nitrogen or argon) in a cool, dry, and well-ventilated environment, protected from moisture and heat, with recommended storage at 2-8°C for long-term stability .
2. Triethoxypropylsilane is classified as a flammable liquid and vapor (Category 3) with a flash point ranging from 45°C to 57°C; GHS hazard statements include H226 (Flammable liquid and vapor), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation) .
3. Personnel must wear chemical-resistant gloves, tightly fitting safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and using explosion-proof electrical equipment and non-sparking tools .
4. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents, strong acids, and strong bases; avoid release to the environment as the substance is harmful to aquatic life (WGK Germany 3) .

1. Isolate the spill area immediately, ensure adequate ventilation, remove all sources of ignition, and evacuate personnel to safe areas; wear full personal protective equipment including chemical-resistant gloves, safety goggles, and appropriate respiratory protection .
2. Collect Triethoxypropylsilane using non-sparking tools by absorbing with inert materials such as sand, diatomaceous earth, or universal binders; a vapor-suppressing foam may be used to reduce vapors .
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 due to potential environmental hazards .
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 .

1. Triethoxypropylsilane CAS 2550-02-9 is a combustible liquid with a flash point of 45-57°C (NFPA fire rating of 2) and boiling point of 179-180°C; under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and silicon oxides .
2. Use dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires involving the product; do NOT use a direct water jet as Triethoxypropylsilane may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning triethoxypropylsilane 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 .
