Colloidal Silica for Coatings Grade Comparison
| Model | SiO₂ Content | Density at 25°C | pH | Shelf Life |
|---|---|---|---|---|
| CC50X | 30±1% | 1.19–1.21 g/cm³ | 9–10 | ≥12 months |
| CC100X | 40±1% | 1.28–1.30 g/cm³ | 9–10 | ≥12 months |
| CC4080 | 40±1% | 1.28–1.30 g/cm³ | 9–10 | ≥12 months |
Values are published technical specifications. Confirm the test method, batch certificate and final acceptance limits before ordering.
Match Solids Level to the Coating Target
Bond Strength and Hardness
CC50X is the 30±1% SiO₂ direction identified for coating trials prioritizing bond strength and hardness.
Gloss-Oriented Evaluation
CC100X provides 40±1% SiO₂ and is identified for formulation trials where gloss improvement is a primary target.
Alternative 40% Grade
CC4080 shares the published SiO₂, density, pH and shelf-life values of CC100X. Request differentiating data before qualification.
Balanced Property Evaluation
CC50X and CC100X can be tested together when a formulation requires a balance of hardness, bonding and gloss.
Information Needed for Coating Grade Evaluation
Provide the binder system, substrate, curing conditions and performance targets so a relevant CC grade can be evaluated in the actual formulation.
- Solids target: confirm whether 30±1% or 40±1% SiO₂ is required.
- Performance target: state the required hardness, adhesion, gloss, heat resistance or balanced profile.
- Substrate and cure: identify the substrate, pretreatment, drying method and cure temperature.
- Compatibility: list the resin or inorganic binder, liquid phase, pigments, fillers and additives.
- Quality requirements: include test methods, certificate requirements and acceptance limits.
- 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.
Colloidal Silica for Coatings Questions
Which colloidal silica grades are available for coating trials?
The published grades are CC50X, CC100X and CC4080.
Which grade targets hardness and which targets gloss?
CC50X contains 30±1% SiO₂ and is identified for bond strength and hardness; CC100X contains 40±1% SiO₂ and is identified for gloss.
Can CC50X and CC100X be evaluated as a blend?
Published guidance states that the two grades may be mixed to obtain a combined performance profile. Validate the ratio in the actual formulation.
What should be checked for coating compatibility?
Check the binder, liquid phase, pigments, fillers, additives, substrate, cure schedule and pH compatibility. All three listed grades have a published pH range of 9–10.
How should colloidal silica for coatings be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container closed. The published shelf life is at least 12 months.

Applications of Colloidal Silica for Coatings
CC50X, CC100X and CC4080 can be evaluated in compatible coating formulations. Grade choice must be validated with the complete binder system, substrate and curing process.
Cookware Coatings
Evaluated in ceramic coating systems for frying pans and other cookware requiring adhesion, hardness, gloss and release performance.
Architectural Aluminum Panels
Suitable for formulation trials on decorative aluminum panel coatings after substrate preparation and cure conditions are confirmed.
Metal Surface Coatings
Can be assessed in non-stick ceramic finishes where bonding and surface durability are key qualification criteria.
Hard Protective Topcoats
CC50X may be evaluated where improved coating bond strength and hardness are prioritized.
High-Gloss Finishes
CC100X may be evaluated where gloss improvement is a primary formulation target.
Custom Coating Formulations
CC50X and CC100X can be tested together to balance their stated performance characteristics in a specific formulation.
