Buyer is looking for liquid sodium silicate with nano silica for producing watertight concrete. The required SiO₂/Na₂O molar ratio is approximately 2.8, nano silica content should be 1.5%–2% of total solids, and total solid content should be 38%–42%.

The buyer would like to test a sample first before placing larger orders. After successful testing, the next order could be approximately 1,000 liters, with potential demand growing to 10,000 liters per year.

The product will be used by a construction company in North Macedonia for waterproof concrete applications, particularly for basements, flooding prevention, and freeze-thaw conditions. Preferred shipping route is via Thessaloniki Port, Greece, or a suitable port in Albania, with delivery expected within approximately 2–3 weeks.
