Chemical Name: N-Aminoethyl-3-aminopropyltrimethoxysilane
CAS Number: 1760-24-3
Content: 70-80%
Other Ingredients: Methanol (CAS 67-56-1, 10-15%), Water (CAS 7732-18-5, 10-15%)
Impurities and Stabilizers: None disclosed above 1% threshold.
Inhalation: Remove person to fresh air, keep comfortable. Administer oxygen if breathing is difficult. Seek medical attention if symptoms persist or worsen.
Skin Contact: Remove contaminated clothing. Wash affected areas thoroughly with soap and water for at least 15 minutes. If rash or irritation develops, contact a physician.
Eye Contact: Rinse cautiously with water for 15 minutes, occasionally lifting eyelids. Remove contact lenses, if present and easy to do. Seek immediate medical attention.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting unless instructed by medical personnel. Give water to drink if conscious. Seek prompt medical care and provide the label/SDS to responders.
Symptoms: Coughing, throat irritation, skin redness, eye pain and damage, dizziness, allergic reaction, nausea.
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or alcohol-resistant foam. Water spray for larger fires may help cool containers.
Unsuitable Media: Do not use direct water jets. May spread flammable liquid.
Specific Hazards: Releases toxic fumes of nitrogen oxides, silicon oxides, and formaldehyde during combustion. Containers may burst under fire conditions.
Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus (SCBA). Approach from upwind, if possible. Collect run-off with care as it may be hazardous.
Special Procedures: Evacuate area. Control runoff to prevent entry into sewers or waterways. Remove flammable materials nearby, ventilate enclosed spaces, and cool containers with water spray.
Personal Precautions: Evacuate unnecessary personnel. Ventilate area. Wear appropriate personal protective equipment (PPE) including chemical-resistant gloves, goggles, and respirator.
Environmental Precautions: Keep away from drains, surface water, and soil. Prevent product from spreading with containment barriers.
Clean-up Methods: Absorb spill with inert material such as sand or vermiculite. Collect residue in suitable chemical waste container and dispose as hazardous waste. Wash area thoroughly with water after material clean-up.
Decontamination: Use water-based cleaning agents. Avoid solvent-based cleaning, which may enhance toxicity.
Handling: Use only in well-ventilated areas. Avoid breathing vapors or sprays. Open containers carefully to avoid spillage. Do not mix with oxidizers, acids, or moisture-sensitive compounds.
Storage: Store in tightly closed, original containers in a cool, dry, well-ventilated place. Keep away from ignition sources, heat, and incompatible substances such as acids and strong oxidizers. Store below 30°C. Keep container upright and away from direct sunlight.
Other Precautions: Keep separate from food or drink. Avoid reuse of empty drums, which may retain hazardous residues.
Exposure Limits: N-Aminoethyl-3-aminopropyltrimethoxysilane: No OSHA PEL/TLV established; Methanol: OSHA PEL 200 ppm (skin), ACGIH TLV 200 ppm (STEL 250 ppm)
Engineering Controls: Use local exhaust ventilation or fume hoods in processing areas. Maintain eye-wash stations and safety showers nearby.
Respiratory Protection: NIOSH-approved respirator recommended for vapor/mist exposures, particularly in poorly ventilated settings.
Skin Protection: Wear nitrile or neoprene gloves. Change gloves if contaminated or damaged. Laboratory coats or chemical-resistant suits recommended.
Eye/Face Protection: Wear chemical splash goggles and face shield.
General Hygiene: Workers should wash hands and face before eating, drinking, or smoking. Remove and wash contaminated clothing before re-use.

Potential Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Oral LD50 (rat): 2295 mg/kg (mixture estimate). Methanol can cause central nervous system depression, visual impairment, and metabolic acidosis.
Chronic Toxicity: Prolonged or repeated skin contact may cause dermatitis. Inhalation may lead to respiratory tract irritation and sensitization. Long-term exposure to methanol may damage organs.
Carcinogenicity: No components classified as carcinogenic by IARC, NTP, OSHA.
Reproductive Effects: Methanol exposure linked to birth defects in animals. No definitive evidence in humans at occupational exposures.
Symptoms of Overexposure: Headache, dizziness, nausea, allergic skin or respiratory reaction, eye pain, blurred vision, unconsciousness (with methanol poisoning).

Persistence and Degradability: Organic aminosilanes gradually degrade in water and soil, but methanol develops toxic breakdown products.
Bioaccumulation Potential: Low bioaccumulation expected, but methanol may be mobile in ground water.
Mobility in Soil: High, particularly for methanol content; may contaminate water supplies if released.
Other Adverse Effects: Avoid release to natural environments. Can disrupt biological treatment systems in municipal wastewater facilities.
Waste Treatment Methods: Dispose of material in accordance with local, state, and federal environmental control laws. Liquid waste requires chemical incineration or disposal via a licensed hazardous waste contractor.
Container Disposal: Rinse containers with water, neutralize rinsate, then dispose in accordance with regulations.
Recommended Disposal: Dilute with water, neutralize with suitable acid, collect in approved vessel, and incinerate under controlled conditions.
Restrictions: Do not pour unused material or mixtures down the drain. Do not landfill untreated liquids.
