Ethyl Trimethoxysilane, with the chemical formula C5H14O3Si, is a silane coupling agent used primarily to improve adhesion between organic polymers and inorganic surfaces. It is supplied as a clear, colorless liquid with low viscosity and is commonly used in coatings, adhesives, and composite manufacturing. The compound hydrolyzes in the presence of moisture to form silanol groups that bond with substrates like glass, metal, or minerals.
Typical industrial grades have a purity of 98% or higher, with methanol and water as the primary impurities. It is stabilized with small amounts of acid inhibitors to prevent premature condensation. The compound is not classified as hazardous under GHS for skin irritation but requires ventilation during handling due to its volatility and flammability. Standard storage is in sealed, moisture-free containers under nitrogen at ambient temperatures.
Buyers include manufacturers of automotive coatings, fiberglass-reinforced plastics, and ceramic adhesives. It is used to enhance bond strength in primer systems and to improve dispersion of fillers in polymer matrices. Packaging is available in 20kg HDPE drums, 200kg steel drums, or bulk tankers. Trade terms are typically FOB Durban or CIF, with lead times dependent on stock availability. MOQ is generally 20kg for direct orders, though larger volumes may be negotiated.

Before ordering Ethyl Trimethoxysilane from Akaba B2B Trading, verify the batch-specific purity, hydrolysis rate, and moisture content through a certificate of analysis. Confirm the CAS number matches 134-18-7 and request a recent GC report. Since no certifications or production details are listed, treat this as a reseller transaction with no quality assurance beyond the supplier’s word.
Confirm the Incoterms offered - likely FOB Durban - and ensure packaging meets your country’s chemical import regulations. Lead time is unknown due to zero response metrics; assume 15 to 25 days. Payment terms are likely T/T in advance. Request written confirmation of shipping documents, including bill of lading, commercial invoice, and GHS-compliant SDS before payment.
Perform incoming inspection using density, refractive index, and viscosity measurements. Check for cloudiness or gel formation, which indicates hydrolysis. Retain a sample from each batch for retesting. Request a copy of the export declaration and chemical registration documentation if importing into the EU or US. Without verified sourcing, third-party inspection is strongly advised.
