3-Isocyanatopropyltrimethoxysilane CAS 15396-00-6

1. 3-Isocyanatopropyltrimethoxysilane is a bifunctional organosilane coupling agent used to improve adhesion between organic polymers and inorganic substrates such as glass, metals, and mineral fillers in adhesives, coatings, and sealants .
2. 3-Isocyanatopropyltrimethoxysilane CAS 15396-00-6 serves as a key intermediate in the synthesis of silane-functionalized polyurethanes and polymers, enabling the introduction of hydrolyzable trimethoxysilyl groups for crosslinking applications .
3. 3-Isocyanatopropyltrimethoxysilane is employed as a surface modifier for the functionalization of silica nanoparticles, glass fibers, and other inorganic materials, enabling covalent attachment of organic molecules .
4. In materials science research, this silane is utilized to create moisture-curable coatings, adhesives, and sealants with enhanced mechanical properties, chemical resistance, and durability .

1. 3-Isocyanatopropyltrimethoxysilane must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from moisture as 3-Isocyanatopropyltrimethoxysilane CAS 15396-00-6 is moisture sensitive; recommended storage at 2-8°C under inert gas .
2. The product is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), H317 (May cause an allergic skin reaction), H334 (May cause allergy or asthma symptoms or breathing difficulties if inhaled), and H335 (May cause respiratory irritation), with signal word "Danger" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, face protection, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and using respiratory protection when necessary .
4. Keep 3-Isocyanatopropyltrimethoxysilane CAS 15396-00-6 away from incompatible materials such as strong oxidizing agents, strong acids, strong bases, and alcohols 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 respirator when 3-Isocyanatopropyltrimethoxysilane is released .
2. For 3-Isocyanatopropyltrimethoxysilane CAS 15396-00-6 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. 3-Isocyanatopropyltrimethoxysilane is a combustible liquid with a flash point of 83-86°C and may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, nitrogen oxides (NOx), 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 3-Isocyanatopropyltrimethoxysilane CAS 15396-00-6 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 3-Isocyanatopropyltrimethoxysilane 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 .
