Colloidal Silica Binder Silica Sol from Linyi Kehan Silicon Products Co., Ltd. is an amorphous silica (SiO2) dispersion in water, engineered for high bonding performance in construction chemicals, refractory applications, and precision casting. The product leverages surface-reactive hydroxyl groups on the silica particles, enabling strong adhesion to carboxyl, amino, and ester functional groups in composite matrices. Typical SiO2 concentrations for such sols range from 20% to 50%, with particle sizes in the nanometer scale, delivering superior binding strength compared to conventional sodium silicate alternatives.
This silica sol is formulated as a stable aqueous dispersion, with particle sizes typically between 5 nm and 40 nm, depending on the grade. The dispersion remains stable at a pH of 8 to 10.5 under standard conditions, carrying an anionic surface charge stabilized by sodium or ammonium ions. The material is supplied in bulk liquid form, commonly packaged in 200L drums or 1000L IBC containers for export, aligning with industry norms for foundry and construction chemical supply chains.
Primary applications include investment casting binders, refractory brick bonding, and coating formulations for paper, ink, and electronic polishing. Global buyers in the ceramics, steel, and construction sectors source this product for its thermal stability and low alkali content, which enhance green strength in molds and cores. Buyers should confirm concentration, particle size distribution, and pH stability with the supplier, as these parameters directly impact performance in high-temperature and chemical-resistant applications.

Before ordering, verify the SiO2 concentration, particle size distribution, and pH stability of the colloidal silica sol, as these parameters directly impact its suitability for your application. Request a certificate of analysis (COA) from Linyi Kehan Silicon Products Co., Ltd. to confirm compliance with your technical specifications, particularly for high-precision uses like investment casting or refractory bonding.
Confirm logistics details, including packaging type (200L drums or 1000L IBC containers), Incoterms (e.g., FOB or CIF), and lead times for bulk shipments. For liquid chemicals, ensure compatibility with your storage and handling systems, and clarify whether the supplier provides export documentation such as MSDS and customs declarations for smooth clearance at your port of entry.
Quality checks should include testing for particle size, viscosity, and pH upon receipt, as variations can affect performance. For critical applications, arrange third-party inspection or request samples for pre-shipment testing. Document all specifications and test results to ensure traceability, and confirm whether the supplier offers technical support for troubleshooting or optimization in your specific use case.
