Chemical Identity: Amino-Modified Polydimethylsiloxane
Chemical Family: Silicone Oils
CAS Number: 63148-62-9 (Base Silicone Fluid), proprietary amine modifier
Concentration: Base polymer 85–99%, amine-functional siloxane 1–10%, non-hazardous additives <5%
Eye Contact: Rinse gently with water for at least 15 minutes, hold eyelids apart; remove contact lenses if present and continue rinsing; seek medical help if irritation persists
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing, wash before reuse; get medical attention for ongoing irritation
Inhalation: Move to fresh air immediately; keep at rest and comfortable; if symptoms like coughing or headache develop, seek medical advice
Ingestion: Rinse mouth; do not induce vomiting unless directed by medical personnel; seek medical assistance if discomfort occurs
Suitable Extinguishing Media: Carbon dioxide, dry chemical, alcohol-resistant foam, water spray
Unsuitable Media: Direct water jets may spread the material
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, formaldehyde, traces of ammonia, silicon oxides
Protective Equipment: Full face self-contained breathing apparatus, chemical protective clothing
Firefighting Advice: Evacuate non-essential personnel, avoid inhaling smoke and fumes; cool exposed containers with water spray
Personal Precautions: Evacuate area, ventilate, avoid contact with skin and eyes, use personal protective equipment (gloves, goggles)
Environmental Precautions: Prevent runoff to sewers, surface water, soil
Spill Cleanup: Cover liquid spill with inert absorbent (sand, earth), collect for disposal in sealed container, clean remaining residue with detergent, avoid direct discharges to the environment
Handling: Handle in well-ventilated areas; use chemical-resistant gloves and safety glasses; avoid inhaling vapor or mist; avoid skin or eye contact; wash hands after use
Storage: Store in a cool, dry, ventilated place; keep containers tightly closed; protect from freezing, high heat, direct sunlight; do not store with food, beverages, or incompatible chemicals such as strong acids, oxidizers
Engineering Controls: Local exhaust ventilation or general dilution ventilation to control airborne concentrations
Personal Protective Equipment: Chemical-resistant gloves (nitrile, rubber), splash goggles, protective clothing (long sleeves, lab coat)
Respiratory Protection: If ventilation inadequate, use a NIOSH-approved organic vapor respirator
Hygiene Measures: Wash hands and face after handling; remove contaminated clothing and wash before reuse; avoid eating, drinking, or smoking in work area
Appearance: Clear to faintly hazy, colorless to light yellow oily liquid
Odor: Mild, amine-like
pH: Not applicable (insoluble in water)
Boiling Point: >200°C (estimated for main polymer)
Flash Point: >100°C (clearly above room temperature, closed cup)
Melting Point: Below -30°C (does not freeze at typical storage temperatures)
Vapor Pressure: Negligible at room temperature
Solubility: Insoluble in water; soluble in most organic solvents
Density: About 0.97–0.99 g/cm³
Viscosity: Varies by grade, typically 100–100,000 cSt at 25°C
Evaporation Rate: Not significant under normal conditions
Chemical Stability: Stable under normal storage and handling conditions
Reactivity: Can react strongly with strong acids, oxidizers, or alkalis; releases hazardous gases in contact with these materials
Hazardous Reactions: None under recommended conditions; improper mixing with incompatible chemicals leads to decomposition
Decomposition Products: Silicon oxides, carbon oxides, formaldehyde, ammonia, nitrogen oxides at high temperatures
Conditions to Avoid: High temperatures, moisture, strong oxidizing conditions, open flames
Likely Routes of Exposure: Inhalation, skin and eye contact, absorption through the skin
Acute Toxicity: Low oral and dermal toxicity (LD50 >5000 mg/kg in rats, typical data for silicone bases)
Skin Corrosion/Irritation: Mild to moderate irritation in animal studies
Eye Damage/Irritation: Moderate conjunctival irritation in rabbit eye studies
Sensitization: Sensitizing in some tests; repeated contact linked to allergic reactions in sensitive individuals
Chronic Effects: Prolonged exposure may lead to dermatitis or respiratory irritation
Carcinogenicity/Mutagenicity: No classification based on available data; not listed by OSHA, IARC, or NTP as a known carcinogen
Other Effects: Inhalation of high vapor concentrations in confined areas may cause dizziness or headache
Aquatic Toxicity: Low solubility and volatility; limited acute toxicity to aquatic organisms, but may be harmful in bulk releases
Persistence and Degradability: Siloxane backbone resists breakdown; contains functional groups subject to slow hydrolysis; persists in environment
Bioaccumulation: Potential for limited bioaccumulation in aquatic organisms due to siloxane structure
Mobility: Non-volatile and insoluble; expected to adsorb to soil or sediment
Other Effects: Large spills may coat water surfaces, affecting oxygen exchange and aquatic life
Waste Disposal: Incinerate in a chemical incinerator equipped with afterburner and scrubber; local and national regulations apply
Contaminated Packaging: Triple rinse containers before disposal; puncture or crush empty drums; follow local hazardous waste requirements
Precautions: Prevent waste from entering drains, water courses, or soil; collect and dispose of spills in approved containers
UN Number: Not regulated by DOT, IATA, or IMDG for most grades
Proper Shipping Name: Non-hazardous for transportation unless mixed with regulated materials
Class: Not classified as dangerous goods for transport
Packing Group: Not applicable
Marine Pollutant: Not classified under IMDG
Special Precautions: Avoid shipment with strong acids, oxidizers; secure load to prevent tipping or breakage
