从China供应商批发进口3-Aminopropylmethyldimethoxysilane — FOB条款

3-aminopropylmethyldimethoxysilane, also known by its CAS number 3069-29-2 or equivalent names A-2120, Z-6023, and KBM-602, is a colorless transparent liquid silane coupling agent with a purity of ≥97% or ≥98%. It has a molecular weight of 206.36 g/mol, a density of 0.960 to 0.980 g/cm³ at 20°C, and a refractive index of 1.4400 to 1.4550 at 25°C. The compound’s amino and methoxy functional groups enable strong adhesion to inorganic substrates like glass, aluminum, and steel.

This silane is typically used to enhance the flexural strength of sand-resin composites while extending the shelf life of resins. It serves as a raw material for synthesizing amino-functional silicones or silicone fluids and can be added to one-part or two-part polysulfide and silicone-crosslinked sealants to improve adhesion. In mineral fiber insulation, it acts as an additive to phenolic resin binders, improving moisture resistance and mechanical properties. Standard industry use includes surface modification of inorganic fillers such as glass beads, silica, talc, mica, and clay.

Buyers of this product are often manufacturers in the composites, adhesives, and sealants industries, as well as producers of insulating materials and foundry sands. It is supplied as a bulk chemical, and buyers should confirm packaging, handling, and storage conditions directly with Qingdao Hengda Zhongcheng Technology Co., Ltd. The product is shipped from Qingdao, Shandong Province, with logistics and trade terms to be agreed upon with the supplier.

Qingdao Hengda Zhongcheng Technology Co., Ltd. is based in Qingdao, Shandong Province, China, with its registered office at Rm B2-2, Floor 13Th, Qingdao International Innovation Park. The company operates in the production and supply of silane coupling agents, including specialty chemicals like 3-aminopropylmethyldimethoxysilane. Its trust tier is classified as harbor, indicating a verified operational presence.

The supplier’s profile does not state a response rate or average response time, so buyers should expect to initiate contact directly to confirm availability, technical specifications, or trade terms.
