*The inorganic CC series can be reviewed for pH adjustment and provides a degree of compatibility with multivalent metal ions. Confirm the target chemistry and actual formulation stability before ordering.
Choose the Modification Route First
Improve Organic-System Compatibility
Hydroxymethyl and vinyl groups support different compatibility and reaction requirements in suitable organic formulations.
Address Ionic Formulation Conditions
CC grades can be evaluated where adjustable pH or compatibility with selected multivalent metal ions is required.
Match Particle Size and Solids
Representative grades span multiple particle-size and SiO₂-content ranges for different formulation targets.
Define the Required Surface Chemistry
Amino and carboxyl surface groups can be reviewed for custom development after the application requirements are confirmed.
Information Needed for a Modified Grade Recommendation
Define the intended interaction with the surrounding formulation before selecting an organic surface group or inorganic modification route.
- Modification objective: describe the compatibility, reactivity or ionic-stability requirement.
- Surface chemistry: specify hydroxymethyl, vinyl, amino, carboxyl or an inorganic direction.
- Silica content: provide the required SiO₂ concentration, pH and tolerances.
- Particle size: provide the target range and measurement method.
- Formulation conditions: identify the resin, solvent phase, metal ions and other critical components.
- Order details: include application, 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.
Modified Colloidal Silica Purchasing Questions
What is modified colloidal silica?
It is a colloidal silica dispersion whose surface chemistry or inorganic stabilization has been adjusted for targeted compatibility, reactivity or formulation stability.
What is the difference between organic and inorganic modification?
Organic modification introduces functional surface groups, while inorganic modification is selected for properties such as adjustable pH and compatibility with selected multivalent metal ions.
Which organic surface groups are available?
Published grades include hydroxymethyl and vinyl groups. Amino and carboxyl groups can be reviewed for customization.
What should be included in an inquiry?
Provide the modification objective, required surface chemistry, SiO₂ content, particle size, pH, formulation components and quantity.
How should modified colloidal silica be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container closed.

Applications of Modified Colloidal Silica
Modified grades are selected when standard colloidal silica does not provide the required compatibility, reactivity or ionic stability. Match the modification route to the complete formulation.
Industrial Coatings
Organic surface-modified grades can be evaluated for compatibility, hardness and drying performance in suitable waterborne systems.
Organic Resin Modification
Hydroxymethyl-functional grades can be selected for compatible resin systems requiring improved silica dispersion.
Reactive Coating Systems
Vinyl-functional grades provide double bonds for evaluation in compatible reactive formulations.
Metal-Containing Formulations
Inorganic modified grades can be tested where selected multivalent metal ions affect dispersion stability.
Inorganic Binders and Ceramics
CC grades can be evaluated as modified silica binders with selectable particle size, solids content and pH.
Custom Formulation Development
Custom amino, carboxyl or adjusted-pH directions can be reviewed for defined application requirements.
