Inhalation: Move affected person into fresh air and keep at rest; seek medical help if symptoms persist; respiratory symptoms can arise after high vapor exposure; remove contaminated clothing
Skin Contact: Wash with plenty of soap and water; remove contaminated clothing; see physician if irritation or rash develops; launder clothes before reuse
Eye Contact: Rinse immediately with clean water for at least 15 minutes, paying careful attention to removing contact lenses if present and easy; consult eye doctor if irritation persists
Ingestion: Rinse mouth; do not induce vomiting; drink small amount of water only if conscious; seek immediate medical attention; risk of methanol poisoning depending on quantity swallowed
Notes for Doctors: Treat based on symptoms; monitor for respiratory distress; methanol exposure requires specific medical intervention
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, water fog
Unsuitable Media: Direct streams of water can spread burning material and vapors
Specific Hazards: Flammable vapors heavier than air accumulate in low areas; combustion releases toxic gases including carbon monoxide, silicon oxides, formaldehyde, organic vapors
Special Protective Equipment: Full protective gear with self-contained breathing apparatus; avoid inhalation of smoke and gases
Fire Fighting Procedures: Remove containers from area if safe; cool exposed drums with water spray; control run-off to avoid environmental impact
Personal Precautions: Evacuate unprotected individuals; isolate spill area; avoid contact with skin and eyes; use personal protective equipment including gloves, goggles, apron
Environmental Precautions: Prevent entry into drains, sewers, waterways, and soil; inform relevant authorities in case of environmental contamination
Clean-Up Methods: Contain spill with absorbent non-combustible material like sand, earth, or diatomaceous earth; collect in suitable, labeled containers for disposal; ventilate spill area
Decontamination: Use detergent solution for final cleaning; avoid use of solvents
Handling: Work in well-ventilated area; keep container tightly closed during use; avoid inhaling vapors and skin or eye contact; no smoking or open flame in storage or use areas; ground all equipment handling contents
Storage: Store in cool, dry, well-ventilated place away from direct sunlight and incompatible chemicals like strong acids, oxidizers, and bases; keep container sealed when not in use
Storage Conditions: Maintain product below 30°C; do not freeze; segregate from food, feed, and potable water
Container Requirements: Use original or approved containers, labeled with contents and hazards
Occupational Exposure Limits: Methanol ACGIH TLV 200 ppm TWA; other components lack established limits but keep exposure as low as possible
Engineering Controls: Local exhaust ventilation recommended; explosion-proof systems wherever vapors may collect; maintain eyewash stations and showers near work area
Personal Protection–Respiratory: Use NIOSH/MSHA-approved respirators in poorly ventilated areas or where exposure limits may be exceeded
Personal Protection–Hands: Wear chemical-resistant gloves (nitrile, butyl rubber recommended)
Personal Protection–Eyes: Safety goggles or face shield
Personal Protection–Skin/Body: Chemical-resistant clothing, apron, and closed-toe shoes
Appearance: Pale, viscous liquid; clear to faintly hazy
Odor: Mild, characteristic to faint fruity
Odor Threshold: Not established
pH Value: Not applicable
Melting/Freezing Point: Not determined (material does not freeze at ambient temperatures)
Boiling Point: >130°C
Flash Point: 36°C (closed cup, depending on formulation)
Evaporation Rate: Slow
Flammability: Flammable liquid
Vapor Pressure: Low at 20°C
Vapor Density: Heavier than air
Solubility: Slightly soluble in water; soluble in organic solvents
Partition Coefficient (n-octanol/water): Not measured
Auto-Ignition Temperature: >200°C
Decomposition Temperature: >150°C
Viscosity: High, depending on grade and formulation
Chemical Stability: Stable under recommended handling and storage conditions
Reactivity: Hydrolyzes slowly in the presence of water, producing methanol
Conditions to Avoid: Heat, flames, sparks, strong alkalis and acids, moisture
Incompatible Materials: Strong acids, oxidizers, bases, source of water, amines
Hazardous Decomposition Products: Methanol (on hydrolysis or curing), Silicon oxides, carbon oxides, formaldehyde (at extreme temperatures)
Polymerization: No dangerous polymerization occurs under normal conditions
Acute Toxicity: Oral LD50 (rat): estimated 2,000-3,000 mg/kg (mixture)
Skin Corrosion/Irritation: Moderate irritation possible after repeated or prolonged exposure
Serious Eye Damage/Irritation: Eye irritation can be significant with direct contact
Respiratory Sensitization: Risk of mild, temporary irritation, especially in unventilated areas
Carcinogenicity: Ingredients not listed as carcinogen by IARC, NTP, or OSHA
Mutagenicity: No data showing mutagenic effects
Reproductive Toxicity: Methanol, formed during curing, is suspected of reproductive effects
Repeated Dose Toxicity: Chronic exposure may increase risk of liver, kidney, and nervous system harm through cumulative methanol exposure
Other Information: Uncured mixture should not be inhaled, ingested or allowed contact with mucous membranes
Ecotoxicity: Limited toxicity to aquatic life; uncured material harmful in large quantities due to methanol formation and hydrolysis byproducts
Persistence and Degradability: Silane backbone degrades slowly in soil and water; hydrolyzes over time
Bioaccumulative Potential: Not highly bioaccumulative; hydrolysis byproducts (methanol) may move through water systems and volatilize
Mobility in Soil: May move through porous soils; significant leaching unlikely in normal spill amounts
Other Adverse Effects: Large amounts can damage aquatic environments by oxygen depletion and pH changes if not confined
Waste Treatment Methods: Do not dispose of in household garbage or sewer; waste must go to approved hazardous waste facility
Container Disposal: Completely empty and rinse containers before recycling or disposal in accordance with local regulations
Special Precautions: Avoid mixing with incompatible wastes, acids, or oxidizers; keep away from sunlight and ignition sources during storage before disposal
Disposal Regulations: Follow regional, national and international environmental laws for hazardous chemical disposal; hazardous waste codes may apply for methanol
