Cleanup Methods: Scoop up with non-sparking tools, collect in clearly labeled containers, clean residue with water and detergent
Disposal: Follow local, national disposal regulations, deliver to licensed waste handler
Additional Measures: Ventilate area after cleanup, prevent vapor build-up
Handling: Handle in well-ventilated spaces, avoid formation of spray or aerosol, wear suitable PPE
Storage Conditions: Store in tightly closed containers, away from direct sunlight and heat sources, keep away from acids and oxidizers
Temperature Range: 5–30 °C recommended
Incompatible Materials: Strong acids, strong bases, oxidizing agents
Other Precautions: Do not reuse empty containers, ensure proper grounding if transferring large quantities

Engineering Controls: Local exhaust ventilation, enclosure of processes, mechanical general ventilation
Personal Protection:
Respiratory: NIOSH-approved respirator with organic vapor cartridge for spray applications
Skin: Chemical-resistant gloves (nitrile, butyl rubber), impervious boots
Eye: Safety goggles with side shields
Body: Long-sleeve protective clothing, apron if splashing possible
Hygiene: Wash hands before eating or drinking, no smoking in work area, remove contaminated clothing promptly

Viscosity: 300–800 cP at 25 °C
Decomposition: Above 180 °C releases volatile amine compounds and minor formaldehyde
Chemical Stability: Stable under recommended storage conditions
Decomposition Products: Amine vapors, silicon oxides, formaldehyde, carbon oxides
Polymerization: Not expected
Reactivity: Reacts with strong acids or oxidizers, can release heat and fumes; forms gels in presence of moisture over time
Conditions to Avoid: Excessive heat, moisture ingress, strong oxidizing environments
Acute Toxicity: Oral LD50 (rat): >5000 mg/kg; Dermal LD50 (rabbit): >2000 mg/kg
Irritation: Moderate skin and eye irritant
Respiratory Sensitization: Prolonged inhalation may cause mild respiratory tract irritation
Chronic Effects: No long-term toxicity data available; based on analogue chemicals, systemic toxicity low
Mutagenicity/Carcinogenicity: Not classified as mutagenic or carcinogenic, trace formaldehyde (IARC 1) present in low quantities

Eco-Toxicity: Not acutely toxic to aquatic life (EC50 Daphnia magna > 100 mg/L)
Persistence and Degradability: Biodegradation slow, hydrolyzes in moist conditions over months
Bioaccumulation Potential: Low, due to large molecular size and poor water solubility
