N-Decyltrimethoxysilane CAS 5575-48-4

1. n-Decyltrimethoxysilane is a long-chain alkyl silane coupling agent primarily used for surface modification to impart hydrophobicity to inorganic substrates such as glass, silica, metals, and minerals .
2. n-Decyltrimethoxysilane CAS 5575-48-4 serves as a water repellent and anti-corrosion coating agent for construction materials, textiles, and automotive applications .
3. n-Decyltrimethoxysilane is employed as a dispersing agent and surface modifier for nanoparticles and fillers to improve compatibility with organic polymer matrices in composite materials .
4. In material science research, n-decyltrimethoxysilane is utilized to create superhydrophobic surfaces, self-cleaning coatings, and corrosion-resistant layers through self-assembled monolayer formation .

1. n-Decyltrimethoxysilane must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from moisture as it is moisture sensitive; recommended storage at 2-8°C under inert gas .
2. n-Decyltrimethoxysilane CAS 5575-48-4 is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition; avoid release to the environment .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when n-Decyltrimethoxysilane is released .
2. For n-Decyltrimethoxysilane CAS 5575-48-4 spills, contain and collect the product using inert absorbent materials such as sand, diatomite, or universal binders with non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating vapors or mists during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. n-Decyltrimethoxysilane is a combustible liquid with a flash point of 66-84°C and may decompose under fire conditions, emitting toxic fumes including 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 n-Decyltrimethoxysilane CAS 5575-48-4 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 n-Decyltrimethoxysilane due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
