Import 3-Aminopropyl Triethoxysilane — Buy in Bulk from Supplier in South Africa

3-Aminopropyl Triethoxysilane (CAS 919-30-2) is a bifunctional organosilane coupling agent with the molecular formula C9H23NO3Si. The molecule contains a primary amine group on one end and three hydrolyzable ethoxy groups on the silicon atom, enabling covalent bonding between organic polymers and inorganic substrates. Akaba B2B Trading supplies this material from South Africa for adhesive, coating, and sealant formulations where interfacial adhesion is critical.

The ethoxy groups hydrolyze in the presence of atmospheric moisture to form silanol groups, which then condense with silanol groups on mineral surfaces or with each other to create siloxane bonds. Typical purity for industrial grades ranges from 98% to 99%, with water content below 0.05% to prevent premature hydrolysis. The standard density is approximately 0.942 g/cm3 at 20 degrees C, and the refractive index at 25 degrees C falls between 1.419 and 1.421. Storage under nitrogen with exclusion of moisture is standard practice to maintain reactivity.

Primary buyers include formulators of epoxy adhesives, polyurethane coatings, and RTV silicone sealants, plus manufacturers of glass fibre reinforced composites and mineral-filled thermoplastics. The amine functionality promotes adhesion to metals, glass, ceramics, and silica while the ethoxy groups react with filler surfaces. For import from Akaba B2B Trading, buyers should confirm the specific grade purity, whether the material is supplied with stabiliser, and the preferred Incoterms for shipment from South African ports.

Akaba B2B Trading operates as an imported supplier tier based in South Africa, holding harbour trust tier status. The listing shows no verification of direct manufacturing capability, indicating the company functions as a trading entity or distributor rather than a primary producer. Response metrics indicate 0.00% response rate with zero average response hours recorded, which suggests limited operational transparency or inactive enquiry management.

The supplier profile does not state years in operation, production capacity, factory location, or workforce size. No certifications are confirmed on the listing, though the source text mentions ISO and CE without verification against this specific supplier. Buyers should treat all certification claims as unverified and request current certificates directly. The company address and warehouse or port facilities are not disclosed, so logistics capabilities from South African origin require explicit confirmation before order commitment.
