Sodium Silicate Liquid
We offer Sodium Silicate in liquid form for specific industrial applications where the liquid property of the chemical is highly effective. We manufacture high-quality silicates that are produced to match our customer's expectations. For special requirements, we customize the liquid so that it can be integrated with the highest efficacy into the products of our clients.
Sodium Silicate Liquid is produced by dissolving silicate solids with water or by a hydrothermal process, which is carried out by reacting caustic lye and fine crystalline silica in autoclaves under intense pressure.
