Applications and sourcing options

Check whether this product fits the buyer's actual application.

Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Use context

Common applications

  • Refractory and heat-resistant material formulations where sodium silicate grade and modulus are specified
  • Construction material bonding applications subject to buyer formulation checks
  • Casting sand binder applications requiring controlled Na2O/SiO2 ratio and insoluble content
  • Industrial water glass feedstock for buyers with their own dissolution and quality-control process
  • Bulk inorganic chemical distribution where jumbo bag handling and export documentation are required
How we compare

Sourcing options

  • Request RFQ for 1 FCL trial order with COA-confirmed 98.5% min total solids.
  • Request sample and pre-shipment COA for ratio 3.20-3.35 before bulk confirmation.
  • Ask for 1000 kg, 1200 kg, or 1250 kg jumbo bag pricing separately.
  • Compare FOB China port and CIF destination port quotes with SDS-based shipping review.
  • Request third-party inspection for packing integrity, batch sampling, and container loading.
  • Ask supplier to quote industrial grade only unless food, pharma, or specialty grade documentation is explicitly required.
Human review

Compliance notes

  • Request current COA, SDS/MSDS, TDS, heavy metal test report, and batch traceability documents before placing an order.
  • Verify CAS 1344-09-8, formula, grade, and HS code against destination-country import requirements.
  • DG classification should be checked with the latest SDS and carrier review; do not rely only on marketplace page text.
  • Confirm whether the product is subject to destination-specific chemical inventory, customs, or industrial-use declarations.
  • Supplier claims certification documents including COA, MSDS, and heavy metal content test report; buyers should review issue date, language, and whether documents match the offered batch.
  • For refractory or construction-material use, confirm required Na2O/SiO2 ratio, total solids, insolubles, moisture, lump size, and any customer-specific impurity limits.
  • No regulatory approval, import clearance, or end-use suitability is guaranteed by the listing; buyer and importer should conduct independent checks.
