Diphenyldiethoxysilane
Diphenyldiethoxysilane is an organosilicon compound with the molecular formula C14H16O2Si and CAS number 6843-66-9, supplied as a colorless transparent liquid with a purity of 98.5%. It functions as a silane coupling agent, enabling adhesion between organic polymers and inorganic substrates through its dual reactivity: ethoxy groups hydrolyze to silanols, while phenyl groups provide organic compatibility.
This compound is commonly used in the production of reactive silicone oils and as an intermediate for other silane coupling agents. In industrial applications, it improves the mechanical strength and moisture resistance of epoxy composites. Typical industry standards for diethoxysilanes include a refractive index between 1.514 and 1.545 at 20°C and a density near 1.08 g/mL at 25°C, values consistent with the listing.
Buyers in the coatings, adhesives, and composite manufacturing sectors use this material to enhance filler-matrix bonding. It is typically packaged in 200kg plastic drums or IBCs. Trade terms such as FOB Huangshan or CIF are standard, but MOQ and lead time are not specified. Buyers should confirm its compatibility with their resin system and request batch-specific test data before use.

Sourcing Diphenyldiethoxysilane from Huangshan City Violet Biological Technology Co., Ltd. - China Import Guide
Before ordering, verify the compound’s purity via a recent Certificate of Analysis using GC or HPLC methods, with emphasis on water content, ethoxy group retention, and absence of phenylsilanol impurities. Confirm the supplier provides a GHS-compliant SDS and batch-specific chromatograms. Do not accept marketing claims without lab data for the actual shipment.
Logistics are typically arranged under FOB Huangshan or CIF terms. Lead time is not specified but generally ranges from 20 to 35 days. Payment terms are commonly 30% advance, 70% against shipping documents. Buyers must confirm Incoterms 2020 version, container type (HDPE drums require ventilation), and insurance coverage for moisture-sensitive cargo.
Perform a pre-shipment inspection to verify drum labeling, seal integrity, and absence of cloudiness or sediment. Request a sample for viscosity and refractive index testing before full acceptance. Ensure the supplier provides a full CoA with test methods, instrument calibration records, and batch traceability. Document any deviations immediately to protect contractual rights.
