Applications & Use Cases
- ▸ Foliar and root-applied silicon source in agriculture, supplying plant-available silica to strengthen cell walls and improve resistance to fungal pressure and abiotic stress in field and greenhouse crops.
- ▸ Inorganic binder and film former in waterborne mineral (silicate) paints, intumescent and high-temperature coatings, and protective primers where it builds a hard, weather- and heat-resistant matrix.
- ▸ Corrosion inhibitor and scale/film-forming agent in industrial water-treatment and cooling-water systems, laying down a protective silica film on metal surfaces.
- ▸ Binder for refractory mortars, foundry molds and cores, welding-electrode coatings, and acid-resistant cements in industrial manufacturing.
- ▸ Deflocculant, detergent builder, and alkaline buffering agent in cleaning and industrial process formulations where soluble silicate raises pH and sequesters hardness.
