Product Name: Silica Sol
CAS No.: 112926-00-8
Molecular Formula: SiO2·nH2O

Properties:
Silica Sol is a kind of colloid which is formed by nm-grade particles SiO2, dispersed in water.

Available Grades:

1. JX Series (Small particle diameter):
- Advantages: Good smooth finish, high precision in size
- Special usage in storage battery industry

2. JA Series (Ammonium stabilized):
- Advantages: Na+ free
- Suitable for high temperature applications and catalyst use

3. ZA Series (Neutral Silica Sol):
- Advantages: No need to adjust pH value for stability
- Practical in coating, ceramics, and catalyst applications

4. JK Series (High drying speed):
- Advantages: 1/2-1/3 of ordinary drying time
- Improved high-temperature resistant performance
- Used in precision casting
