Custom Colloidal Silica Questions
Which colloidal silica parameters can be customized?
Projects may review particle size, solids, pH, stabilizing ion, surface modification, impurity limits, viscosity, packaging and documentation.
Can any particle size and concentration be combined?
No. Particle size, concentration, pH and stabilizer affect viscosity and colloidal stability. Each requested combination requires a feasibility review.
Is an application sample required?
Yes. Custom grades should be evaluated in the full formulation and representative process before the specification is approved for scale-up.
Can custom purity limits be reviewed?
Yes. Provide each controlled element, numerical limit, unit, sampling basis and test method so technical feasibility can be assessed.
What determines custom development lead time?
Lead time depends on specification complexity, analytical methods, sample iterations, application testing, packaging and quality-document requirements.

Where Custom Colloidal Silica Adds Value
Custom development is most useful when a standard grade fails a measurable compatibility, purity, particle or process requirement.
Precision Casting
Match binder solids, particle size and slurry stability to face or backup shell requirements.
Catalyst Systems
Review surface area, purity, stabilizer, pore development and calcination behavior.
CMP and Electronics
Control particle distribution, metal ions, sodium, pH and polishing consistency.
Functional Coatings
Adjust charge, surface modification and compatibility for adhesion, hardness or substrate interaction.
Battery Materials
Evaluate high-purity, low-ion or modified grades for separator and component-coating research.
Paper and Textile
Match cationic or modified particle behavior to fibers, retention chemistry, sizing and surface coating.
