3-Aminopropyltrimethoxysilane (CAS 13822-56-5) from Qingdao Hengda Zhongcheng Technology Co., Ltd. is a colourless transparent liquid silane coupling agent with molecular weight 179.28 and refractive index (n25D) of 1.4205 to 1.4225. The supplier lists purity grades of greater than or equal to 97% and greater than or equal to 98%, with a density at 20 degrees Celsius of 1.005 to 1.015 g/cm3. This organofunctional silane bears both a primary amine group and three methoxy silane groups, enabling dual reactivity with organic polymers and inorganic surfaces.
Structurally, the molecule consists of a three-carbon propyl chain terminated by an amino group at one end and a trimethoxysilyl moiety at the other. The methoxy groups hydrolyse in the presence of moisture to form silanol groups, which then condense with siliceous surfaces or each other. Typical industrial applications require controlled moisture levels during handling to prevent premature hydrolysis. The amine functionality provides basic catalytic activity and reactivity with epoxies, isocyanates, and phenolic resins.
Primary buyers include manufacturers of phenolic moulding compounds, epoxy adhesives, polyamide composites, and polybutylene terephthalate formulations. Foundry sand binders, coating formulators, and sealant producers also source this material. Trade is typically conducted in bulk liquid containers with standard hazmat documentation for chemical shipments from Shandong Province. Buyers should confirm packaging specifications, exact purity grade, and storage conditions directly with the supplier.

Before ordering 3-aminopropyltrimethoxysilane from Qingdao Hengda Zhongcheng Technology Co., Ltd., verify the supplier's business licence and chemical production or trading permit through Shandong provincial authorities. Request a current certificate of analysis for the specific batch, confirming the purity grade, refractive index, and density values match your formulation requirements. Ask for references from existing export customers in your region, particularly regarding product consistency and documentation accuracy. Confirm that the supplier understands and can comply with your country's chemical import notification requirements, such as REACH pre-registration for EU buyers or TSCA filing for US destinations.
Logistics from Qingdao Port typically involve sea freight for liquid chemicals in properly classified containers. Buyers should clarify Incoterms with the supplier, whether FOB Qingdao or another arrangement, and confirm who arranges hazmat booking and export customs clearance. Lead times are not stated and must be confirmed directly, factoring in Chinese public holidays and potential port congestion in Shandong. Payment terms vary by relationship and order volume; common structures include 30% advance with balance against copy of B/L, or letter of credit for initial transactions. Insist on marine insurance covering chemical leakage or container damage during transit.
Upon arrival, conduct independent quality testing of the batch before accepting goods into inventory. Key tests include gas chromatography for purity, Karl Fischer titration for moisture content, and refractive index measurement at 25 degrees C to verify specification compliance. Inspect packaging integrity for signs of moisture ingress, such as cloudiness or viscosity change. Retain samples from each batch for traceability. Ensure all customs documentation, including commercial invoice, packing list, bill of lading, and SDS, matches the actual shipment contents and your import licence scope.
