Product Features
This series consists of high solid-content nano silica sol products, with solid content up to 50%. Under the same dosage, they provide more active ingredients, significantly reducing transportation and drying costs. The products combine high purity with excellent dispersion stability, making them suitable for investment casting, refractory materials, specialty coatings, and composite materials where high solid content and bonding strength are required.
Note: The particle size of each model can be customized according to customer requirements.
Packaging Specifications
Packed in polyethylene plastic drums, available in 25 kg, 250 kg, and 1000 kg specifications.
Storage Conditions
Avoid direct sunlight; storage temperature should be controlled between 5–40°C.
Storage temperature must not fall below 0°C; low temperatures can cause the colloid to freeze and result in permanent failure.
Containers must be sealed and kept closed for extended periods. Evaporation of water will cause silica particles to precipitate, directly affecting product performance.
