从China供应商批发进口3-Aminopropyltriethoxysilane 919-30-2 — FOB条款

3-Aminopropyltriethoxysilane, identified by CAS number 919-30-2, is a colorless transparent liquid silane coupling agent with a purity of ≥98%, ≥99%, or ≥99.5%. It has a molecular weight of 221.34 g/mol, a density of 0.935 to 0.955 g/cm³ at 20°C, and a refractive index of 1.4135 to 1.4235 at 25°C. Known by equivalent names A-1100, Z-6011, and KBE-903, this product is widely used to improve the bond between organic and inorganic materials.

In industrial applications, this silane enhances the physical and electrical properties of mineral-filled thermoset and thermoplastic composites, such as epoxies, polyamides, and polybutylene terephthalate. It improves filler wetting and dispersibility in polymer matrices, which is critical for achieving uniform material properties. In shell molding, it strengthens the bond between phenolic binders and foundry sand, while in coatings and adhesives, it acts as an adhesion promoter for substrates like glass, aluminum, and steel.

The primary buyers of this product are manufacturers in the fiberglass, composites, and coatings industries. It is supplied in bulk from Qingdao, Shandong Province, and buyers should confirm packaging, handling, and storage requirements directly with Qingdao Hengda Zhongcheng Technology Co., Ltd. Trade terms, including Incoterms and payment methods, are to be negotiated with the supplier.
