Safety and handling
Corrosive handle with protection
Contact causes severe skin and eye burns, so chemical-resistant gloves and eye protection are required when handling.
- Reacts with acids to precipitate insoluble silica gel and release heat keep strictly separated from acid storage.
- Store in tightly sealed containers at moderate temperatures; protect from freezing to preserve viscosity and consistency.

Frequently asked questions

Sodium silicate's properties (viscosity, alkalinity, bonding strength) depend on its SiO₂ to Na₂O ratio. Different ratios suit different jobs, detergent building needs one range, adhesives and foundry binding need another. Tell us your application and we'll confirm the right ratio.
Yes. It's corrosive and can cause severe skin and eye burns on contact, so standard handling requires gloves and eye protection. It is not flammable.
Sodium silicate ships in 35kg, 40kg, and 50kg containers, IBC totes for larger volumes, or bulk. Our minimum order quantity is 500kg; above that, we supply any quantity your production needs.
In sealed containers, at moderate temperature, away from acids and freezing conditions, since freezing can affect its consistency.
