Import 3-Glycidoxypropyltrimethoxysilane — Buy in wholesale FOB from Supplier in China

3-glycidoxypropyltrimethoxysilane from Huangshan City Violet Biological Technology Co., Ltd. is a silane coupling agent with CAS number 2530-83-8 and EINECS 219-784-2, supplied as a colourless transparent liquid with colour index No. 0 and a density of 1.007 g/mL at 25 degrees Celsius. The compound has a molecular formula of C9H20O5Si and a boiling point of 299.4 degrees Celsius, with a refractive index of 1.428 and acidity at neutral pH 6 to 7. The supplier states a minimum purity of 98.5 percent, and packages the material in 20 kg or 200 kg iron or plastic drums, 1000 kg IBC drums, or 20 MT tank containers.

This silane features a glycidoxy functional group and three methoxy groups attached to a propylsilane backbone, making it reactive toward both organic resins and inorganic substrates. The glycidoxy ring opens under curing conditions to form covalent bonds with hydroxyl-bearing surfaces, while the methoxy groups hydrolyse to silanols for substrate adhesion. Typical industrial grades of analogous silane coupling agents range from 98 to 99 percent purity, with moisture content below 0.1 percent being standard for storage stability. The neutral pH indicates minimal residual acidic or basic catalyst, which is critical for applications in sensitive polyester systems where premature curing or degradation must be avoided.

The primary application for this material is in unsaturated polyester composite materials, where it functions as an adhesion promoter between glass fibre reinforcements and the polymer matrix, improving mechanical properties such as flexural strength and interlaminar shear. Buyers include manufacturers of fibre-reinforced plastics, automotive components, marine craft, and construction materials. Importers should confirm the exact packaging specification, shelf life, and whether the drums are nitrogen-purged to prevent moisture ingress, as silanes are highly moisture-sensitive and can gel or lose reactivity upon hydrolysis. The supplier is based in Huangshan Economic Development Zone, Anhui Province, and operates under the trust tier classification of harbour with no recorded response rate or average response time in the available data.

Huangshan City Violet Biological Technology Co., Ltd. is located in Huangshan Economic Development Zone, Anhui Province, China, with postal code 245000. The company operates under the trust tier classification of harbour, but records a response rate of 0.00 percent with an average response time of zero hours, indicating that no response data is currently available for this supplier profile. The listing provides no information about the year of establishment, registered capital, number of employees, annual revenue, factory size, or specific production capacity for 3-glycidoxypropyltrimethoxysilane.

The supplier markets this silane coupling agent with reference to established industry equivalents from Union Carbide (A-187), Dow Corning (Z6040), and Shin-Etsu (KBM403), positioning the product within recognised technical standards. No certifications, quality management systems, export licences, or client references are stated in the available profile. Buyers should independently verify the supplier's manufacturing capabilities, quality control procedures, and whether the facility operates under ISO or equivalent standards before committing to a purchase. The absence of response metrics suggests that direct enquiry through available channels is essential to assess commercial viability and communication reliability.
