Impurities: Methanol may be present in trace amounts stemming from hydrolysis.
Other Ingredients: No additional hazardous components identified.
Inhalation: Move to fresh air immediately. Provide oxygen if breathing is difficult. Call for medical attention if symptoms persist or develop.
Skin Contact: Remove contaminated clothing immediately. Rinse skin with plenty of running water for at least fifteen minutes. Seek medical advice if irritation or redness develops.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek immediate medical attention.
Ingestion: Do not induce vomiting. Rinse mouth with water if victim is conscious. Seek medical advice immediately.
Notes for Physicians: Treat symptomatically. Watch for pulmonary edema and chemical burns.
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, or carbon dioxide. Do not use water jet.
Specific Hazards: Vapors can form explosive mixtures with air. Ammonia or nitrogen oxides may form under fire conditions. Methanol may be released through hydrolysis.
Protection for Firefighters: Wear self-contained breathing apparatus and full protective clothing for chemical fires. Avoid inhaling combustion products.
Special Procedures: Move containers from fire area if safe. Cool exposed containers with water spray. Prevent fire-fighting water from entering drains or waterways.
Personal Precautions: Wear chemical splash goggles, impervious gloves, and protective clothing. Avoid contact with spilled product. Avoid inhaling vapors.
Environmental Precautions: Prevent entry into sewers, groundwater, or surface water. Notify relevant authorities in the event of major environmental contamination.
Methods for Clean Up: Absorb spill using inert material like dry sand or earth. Collect material in tightly sealed containers for disposal. Wash spill site after complete clean-up.
Containment and Neutralization: For large spills, dike area to contain and prevent spread. Use non-combustible absorbents.
Handling: Keep containers tightly closed when not in use. Use explosion-proof equipment and grounded containers. Avoid exposure to air and moisture. Always work in a fume hood or well-ventilated space. Wash hands and face after handling.
Hygiene Practices: Do not eat, drink, or smoke around the product. Wash contaminated clothing before reuse.
Storage: Store in a dry, cool, and well-ventilated area. Keep away from sources of ignition, heat, and direct sunlight. Store separately from acids, oxidizers, and water. Keep container tightly sealed. Avoid contact with moisture to prevent methanol formation.
Occupational Exposure Limits: No specific TLV or OSHA PEL listed for this compound. Consider methanol exposure limit if hydrolysis is possible.
Engineering Controls: Use local exhaust ventilation or chemical fume hood to minimize vapor exposure. Emergency showers and eyewash stations should be accessible.
Personal Protective Equipment: Wear chemical-resistant gloves such as nitrile or neoprene. Use splash-proof safety goggles and a face shield. Don lab coat or chemical-resistant suit. If vapor exposure is possible, use an approved respirator.
Additional Measures: Remove contaminated clothing immediately. Follow company safety procedures and risk assessments. Conduct regular workplace monitoring.
Appearance: Colorless to pale yellow clear liquid

Molecular Weight: 206.36 g/mol
Boiling Point: 225°C (437°F)
Melting Point: Not established (liquid under ambient conditions)
Flash Point: ≥107°C (225°F, closed cup)
Vapor Pressure: <1 mmHg at 20°C
Solubility: Hydrolyzes in water; soluble in alcohols and most organic solvents
Density: 1.01 g/cm³ at 25°C
pH: Alkaline on hydrolysis
Partition Coefficient (log Kow): Not available
Viscosity: Not available
Chemical Stability: Stable under recommended storage and handling conditions. Decomposes in contact with water or humid air, forming methanol and silanols.
Conditions to Avoid: Heat, flames, ignition sources, moisture, and strong acids or oxidizers.
Incompatible Materials: Strong acids, oxidizing agents, water, alcohols, and strong bases. Reacts with acids to release heat and potentially hazardous gases.
Hazardous Decomposition Products: Methanol, formaldehyde, ammonia, nitrogen oxides, silicon oxides.
Polymerization: Not expected under normal conditions.
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat): 2290 mg/kg (literature value, may vary)
Skin Corrosion/Irritation: Causes severe burns, possible permanent damage
Eye Damage/Irritation: Causes irreversible eye damage, risk of blindness
Respiratory Sensitization: May provoke burning sensation and respiratory discomfort
Chronic Effects: Prolonged exposure may cause dermatitis, chemical burns, or organ damage. Methanol formed by hydrolysis is a toxic alcohol, may cause systemic toxicity.
Carcinogenicity/Mutagenicity: No data available for this compound as a carcinogen or mutagen.
Other Effects: May aggravate pre-existing skin, respiratory, or eye conditions.
Ecotoxicity: Product can be toxic to aquatic life due to high alkalinity and amine content. Can cause long-term harmful effects to aquatic environments if discharged in large volumes.
Persistence and Degradability: Reacts rapidly with water, forming silanols and methanol, which degrade under environmental conditions.
Bioaccumulation Potential: Not expected to bioaccumulate significantly owing to reactive nature and hydrolysis products.
Mobility in Soil: Decomposes on contact with moist soil, limited mobility due to binding with substrates.
Other Adverse Effects: Spills may increase pH of water and soil, impacting aquatic life and microorganisms.
Waste Handling: Dispose of in accordance with local, regional, and national regulations. Do not mix with household waste or pour down the drain.
Recommended Disposal Method: Incinerate under controlled conditions using a licensed chemical waste disposal contractor. Dispose of contaminated packaging the same way as product.
Precautions: Neutralize residues with dilute acid before handling further. Avoid releases to the environment. Follow all environmental and safety guidelines for disposal.
Additional Advice: Consult a licensed waste disposal company to ensure compliance.
