Composition / Information on Ingredients

Main Ingredient: Aminosilane hydrolysate (CAS number varies by specific aminosilane type, typically in range 20–50%)
Solvent: Deionized Water (balance; 50–80%)
Byproducts/Impurities: Trace methanol or other alcohols (produced on hydrolysis, <0.5%)
Other Components: No ingredients present above regulatory disclosure thresholds outside of main silane component

First Aid Measures

Inhalation: Move person to fresh air, keep comfortable, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash thoroughly with soap and water, get medical help for persistent irritation
Eye Contact: Rinse cautiously with water for at least 15 minutes, remove contact lenses if present, seek medical attention immediately
Ingestion: Rinse mouth, do not induce vomiting, drink water in small quantities, seek medical help immediately
Most Important Symptoms: Redness, dermatitis, chemical burns in severe cases

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: Direct water stream may cause splattering
Specific Hazards: Vapors may generate upon heating; some thermal decomposition products (e.g. nitrogen oxides, silicon oxides) can be irritating/toxic; presence of trace alcohols
Protection for Firefighters: Wear self-contained breathing apparatus, chemical protective clothing
Special Procedures: Cool exposed containers with water spray to prevent pressure build-up

Accidental Release Measures

Personal Precautions: Wear protective clothing including gloves and goggles, work in a well-ventilated area
Environmental Precautions: Prevent product from entering drains, surface water, or soil
Spill Containment: Surround with inert absorbent (e.g., vermiculite, sand), cover drains, ventilate area
Cleanup Methods: Use non-sparking tools to collect, place in suitable containers for disposal, clean residues with water
Reporting: Notify responsible authorities if significant spillage or environmental release

Handling and Storage

Handling Precautions: Avoid skin and eye contact, do not breathe vapors or aerosols, use in well-ventilated places
Storage Conditions: Store in cool, dry, well-ventilated area away from incompatible materials such as strong acids or bases; keep container tightly closed
Incompatible Materials: Strong oxidizers, acids, bases, moisture-sensitive substances
Special Storage Instructions: Protect from freezing, avoid direct sunlight and extreme temperatures; use only non-metallic or coated containers
Handling Bulk Quantities: Use secondary containment and ground all equipment to prevent static discharge

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limits for aminosilane hydrolysate; keep below nuisance dust/vapor limits
Engineering Controls: Use local exhaust, general dilution ventilation, enclosure of operations
Personal Protective Equipment: Chemical-resistant gloves, splash goggles or face shield, lab coat or apron, closed shoes
Respiratory Protection: Use appropriate respirator if ventilation is inadequate
Hygiene Measures: Wash hands after handling, remove contaminated clothing, avoid eating/drinking/smoking in work area

Physical and Chemical Properties

Appearance: Clear to slightly hazy liquid
Color: Colorless to pale yellow
Odor: Amine-like
pH: 10–12 (alkaline)
Melting/Freezing Point: Near water freezing (0°C)
Boiling Point/Range: 100–110°C (depends on water content)
Flash Point: Not applicable (aqueous solution)
Evaporation Rate: Similar to water
Vapor Pressure: Similar to water
Specific Gravity: 1.01–1.06 at 20°C
Solubility in Water: Fully miscible
Viscosity: Low (like water)
Decomposition Temperature: Decomposes at high temperatures to produce nitrogen/silicon oxides

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: May react with strong oxidizers, acids, bases
Hazardous Reactions: Contact with acids releases heat; may form trace methanol or other alcohols during hydrolysis
Conditions to Avoid: Avoid excessive heat, freezing, direct sunlight, contact with incompatible substances
Hazardous Decomposition Products: Nitrogen oxides, silicon oxides, trace formaldehyde, trace methanol

Toxicological Information

Acute Toxicity: Skin and eye irritation common; ingestion shows moderate toxicity; low vapor toxicity but high concentrations can irritate respiratory tract
Chronic Toxicity: No evidence points to carcinogenicity or mutagenicity; overexposure can cause dermatitis or respiratory sensitization
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Symptoms: Redness, itching, burning sensation, dermatitis possible; chronic exposure can worsen skin conditions
LD50/LC50 Values: Consult specific aminosilane datasheet; for similar compounds, oral LD50 (rat) is typically >2,000 mg/kg

Ecological Information

Aquatic Toxicity: Not acutely toxic to fish or aquatic invertebrates at product concentrations; large spills may disrupt pH balance
Persistence/Degradability: Moderate; hydrolyzes in the environment to inorganic silicates and organic amines
Bioaccumulation Potential: Low for silicate residues; amine components can be more mobile
Mobility in Soil: High, water solubility ensures spread; slows on hydrolysis
Other Adverse Effects: Overuse or spillage may affect aquatic and microbial life, particularly with repeated exposure

Disposal Considerations

Waste Disposal: Dispose of contents/container in accordance with local, state, and national laws
Recommended Disposal Methods: Incineration in approved facility, or treatment in wastewater plant capable of handling organosilane compounds
Special Precautions: Avoid contaminating water supplies; do not pour down drain or into surface water
Empty Containers: Rinse thoroughly; recycle or dispose according to environmental legislation

Transport Information

UN Number: Not typically regulated for transport in dilute aqueous forms; check with logistics provider
Transport Hazard Class: Non-hazardous for most transport modes; flammable vapors possible only with high methanol content
Packing Group: Not required, except in cases where alcohol content exceeds DOT regulatory thresholds
Special Precautions for Transport: Avoid freezing, keep sealed and upright, segregate from acids/oxidizers
Environmental Hazards during Transport: Spill containment preferred in transit, label and document as precaution

Regulatory Information

US Regulations: Subject to TSCA (Toxic Substances Control Act) inventory reporting; SARA Title III reporting not typically triggered at working concentrations
EU Regulations: REACH-registered for most primary aminosilanes; no major restrictions on use, but observe workplace exposure directives
Labelling Requirements: GHS pictogram, precaution and hazard statements as per classification
Other Jurisdictions: Reference local regulatory status for specific compound CAS number, workplace air limits, and environmental discharge limits
Worker Protection Law Compliance: Ensure training in safe handling and emergency procedures for all staff
