Description of key information
Table. Degradation rates
Degradation rate in water: |
Hydrolysis half-life (isocyanate group): <5 minutes at pH 7. Hydrolysis half-life (triethoxysilane group): 8.5 h at pH 7. No significant biodegradation expected for the final silanol hydrolysis product (3-aminopropylsilanetriol). |
Degradation rate in sediment: |
No significant biodegradation expected for the final silanol hydrolysis product (3-aminopropylsilanetriol). |
Degradation rate in soil: |
No significant biodegradation expected for the final silanol hydrolysis product (3-aminopropylsilanetriol). |
Degradation rate in air: |
Half-life for reaction with hydroxyl radicals in air: 0.7 days for parent; 0.3 days for intermediate silanol hydrolysis product, 3-aminopropyltriethoxysilane and 0.4 days for silanol hydrolysis product, 3-aminopropylsilanetriol (predicted). |
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
