Application

1. Anti-oil agent, stuffing agent and corrosion buffer
2. Binder for making fire-resistant material
3. Cement fast-drying agent in constructing industry
4. Water soluble silicon fertilizer
5. Stuffing and strengthening material in oil drilling and tunnels
6. Many other industries like metallurgy, electronics, refractory, casting and etc.

Important Notice

1. Sodium silicate can be made from different raw material, the mostly used are:
  - Sodium Sulphate + quartz sand (we call it SSA process)
  - Soda ash + quartz sand (we call it Soda Ash process)
According to Rawchem's experience, SSA process product can not be used in detergent industry due to its color and quality stability problems, so we only use soda ash process for detergent industry clients

2. There are different types of sodium silicate, just by the name "sodium silicate", normally we can not define which item exactly it is, to quote or offer, we need to know the following info:
  - Liquid or solid
  - Modules

3. 24 months when stored in cool, dry and ventilated warehouse, away from incompatible materials
