*Published product-family envelope. The available combination depends on stabilization chemistry and is not a simultaneous specification for one standard grade. Confirm water quality, target values and test methods before sampling.
Specify the Water-Based Dispersion
Confirm Dispersion-Water Quality
Define deionized-water and conductivity requirements where trace ions affect formulation performance.
Match the Required pH System
Select acidic, alkaline, ammonium, potassium, low-sodium or modified stabilization for compatibility.
Set the Working Concentration
Confirm supplied SiO₂ content together with dilution, mixing and final-solids requirements.
Choose Particle Size
Particle size affects surface area, reactivity, packing behavior and interaction with other components.
Information Needed for Aqueous Grade Selection
Provide both the colloidal silica targets and the surrounding water-based formulation conditions.
- Dispersion medium: state deionized-water, conductivity and permitted ionic-content requirements.
- Core parameters: provide SiO₂ content, particle size, pH, density and viscosity targets.
- Stabilization chemistry: specify acidic, alkaline, ammonium, potassium or another required system.
- Dilution conditions: provide dilution water, mixing order, shear level and operating temperature.
- Compatibility: list binders, additives, pigments, surfactants and other formulation components.
- Order details: provide trial quantity, annual demand, packaging and destination country.

Packaging Options
Available polyethylene packaging sizes are 25 kg, 250 kg and 1000 kg.
Storage Temperature
Store at 0–40°C and protect from freezing. Temperatures below 0°C can cause irreversible gelation.
Direct Sunlight
Avoid prolonged exposure to direct sunlight during storage and transportation.
Container Closure
Keep containers closed to limit water evaporation and precipitation of solid silica particles.
Aqueous Colloidal Silica Purchasing Questions
What is aqueous colloidal silica?
It is a stable water-based dispersion of amorphous silica nanoparticles, also commonly called silica sol.
Does the water quality matter?
Yes. Conductivity and dissolved ions can affect sensitive formulations, so water-quality requirements should be stated when relevant.
Can aqueous colloidal silica be diluted?
Dilution may be possible, but the water quality, addition order, mixing conditions and resulting stability must be validated.
Which parameters should buyers specify?
Specify SiO₂ content, particle size, pH, density, viscosity, stabilization chemistry and impurity limits.
How should aqueous colloidal silica be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container closed.
