3-triethoxysilylpropan-1-amine

3-triethoxysilylpropan-1-amine is an organosilane coupling agent with the molecular formula C9H23NO3Si and CAS number 919-30-2. This aminosilane compound features both amino and triethoxysilyl functional groups, making it valuable for surface modification and adhesion promotion. With a molecular weight of 221.37 g/mol, it serves as a bridge between organic and inorganic materials in various industrial applications.

3-triethoxysilylpropan-1-amine is typically a clear to pale yellow liquid at room temperature with a characteristic amine odor. The compound is moisture-sensitive and readily hydrolyzes in the presence of water, forming silanol groups. It is soluble in most organic solvents including alcohols and hydrocarbons but reacts with water. The molecular structure contains both hydrolyzable ethoxy groups and a basic amino functionality.

3-triethoxysilylpropan-1-amine is primarily used as a coupling agent and surface modifier in composite materials, adhesives, and sealants. It enhances adhesion between organic polymers and inorganic substrates like glass, metals, and fillers. Common applications include fiber glass reinforcement, paint formulations, primer systems, and as a surface treatment for mineral fillers in rubber and plastic compounds to improve mechanical properties and durability.

3-triethoxysilylpropan-1-amine requires careful handling due to its corrosive nature (Skin Corr. 1B) and acute toxicity (Acute Tox. 4). Essential PPE includes chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation. Avoid skin and eye contact, and prevent inhalation of vapors. Keep away from moisture and incompatible materials during handling operations.

3-triethoxysilylpropan-1-amine must be stored in tightly sealed containers in a cool, dry place away from moisture and heat sources. Keep containers in well-ventilated areas away from incompatible materials such as strong acids, bases, and oxidizing agents. Store in original containers with proper labeling and ensure temperature stability. Protect from direct sunlight and maintain storage areas with appropriate spill containment measures.

3-triethoxysilylpropan-1-amine contact requires immediate action due to its corrosive properties. For skin contact, immediately remove contaminated clothing and flush with plenty of water for at least 15 minutes. For eye contact, rinse immediately with water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air and seek medical advice. Never induce vomiting if swallowed and seek immediate medical attention.

3-triethoxysilylpropan-1-amine disposal must comply with local and national hazardous waste regulations as it is classified as dangerous goods. The waste should be collected by licensed hazardous waste disposal companies and cannot be disposed of with regular waste. Containers should be completely emptied and may require special treatment. Consider recycling or recovery options where available, and maintain proper documentation of disposal activities as required by law.

3-triethoxysilylpropan-1-amine is classified as ADR Class 8 (corrosive substances), Packing Group II, requiring specific transport protocols. Packages must meet UN specification standards and display appropriate hazard labels including GHS05 and GHS07 pictograms. Transport vehicles need proper placarding and emergency equipment. Drivers require ADR training certification, and shipping documentation must include proper shipping names, hazard classifications, and emergency response information.

3-triethoxysilylpropan-1-amine is subject to REACH regulation requiring registration for manufacture or import above 1 tonne annually in the EU. CLP regulation mandates specific labeling with 'Danger' signal word and appropriate pictograms (GHS05, GHS07). It is not currently listed as an SVHC substance. Users must comply with occupational safety regulations, maintain safety data sheets, and follow workplace exposure limits where established by national authorities.

3-triethoxysilylpropan-1-amine is available through OYSI, a specialized European distributor of technical chemicals serving industrial customers across Europe. OYSI provides reliable supply chains, technical support, and regulatory compliance assistance for professional users. The compound is typically available in various packaging sizes to meet different application requirements, with proper documentation including certificates of analysis and safety data sheets for safe industrial use.
