Ludox Silica Sol Alternative Selection
Trademark notice: LUDOX® is a trademark associated with W. R. Grace & Co. Peak-tech is an independent colloidal silica manufacturer and is not affiliated with, authorized by or endorsed by the trademark owner. Brand references are used only to describe a buyer's replacement-selection requirement.
Peak-tech develops colloidal silica sol candidates by matching the buyer's required particle size, SiO₂ content, pH, stabilizing ion, purity and process behavior. No equivalence should be assumed without document review and application testing.
| Peak-tech Evaluation Range | SiO₂ Content | Particle Size | pH Range | Density | Viscosity |
|---|---|---|---|---|---|
| Custom Silica Sol Candidate | 20–40 wt% | 3–180 nm | 2.0–10.5* | 1.10–1.30 g/cm³* | <10 mPa·s* |

Build the Alternative Around Measurable Requirements
Submit the Current Specification
Provide the current product TDS, COA or a target specification without relying only on a brand or grade name.
Compare Critical Parameters
Align particle size and method, SiO₂ content, pH, stabilizing ion, density, viscosity and impurity limits.
Evaluate Process Compatibility
Test mixing, dilution, storage stability, binder interaction, drying or curing behavior in the actual formulation.
Approve by Application Trial
Adopt a candidate only after agreed laboratory, pilot and finished-product acceptance criteria are met.
Information Needed for Alternative Evaluation
A third-party grade name alone is insufficient because specifications, test methods and process response must all be compared.
- Reference document: provide the current TDS, recent COA or complete target specification.
- Particle data: state nominal size, distribution, tolerance and measurement method.
- Liquid properties: provide SiO₂ content, pH, stabilizing ion, density, viscosity and appearance.
- Purity limits: specify sodium, total metals or element-specific requirements and analytical methods.
- Application conditions: include other ingredients, mixing order, temperature, dilution water, drying and curing conditions.
- Acceptance tests: define storage stability, bonding, polishing, coating or other application-specific criteria.
- Commercial details: include trial quantity, annual demand, packaging and destination country.
Request an Independent Silica Sol Alternative Review
Send the reference TDS or target parameters, application conditions, acceptance tests, trial quantity and annual demand. Peak-tech will evaluate a technical candidate without claiming automatic equivalence.

Packaging Options
Published 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 reduce water evaporation, contamination and silica precipitation.
Ludox Silica Sol Alternative Questions
Does Peak-tech manufacture LUDOX products?
No. Peak-tech manufactures its own colloidal silica products and is not affiliated with or authorized by the owner of the LUDOX trademark.
Are Peak-tech grades automatically equivalent to a named third-party grade?
No. A candidate must be compared using the required specification, test methods and actual application performance before approval.
What should be provided for a cross-reference review?
Provide the current TDS or COA, particle-size method, solids content, pH, stabilizer, purity limits, application conditions and acceptance tests.
Why is an application trial required?
Products with similar headline parameters can behave differently during mixing, storage, drying, curing, bonding or polishing. Testing verifies suitability in the buyer's process.
How should a silica sol sample be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container securely closed.

Silica Sol Replacement Qualification Scenarios
These are application areas for independent Peak-tech candidate evaluation. They do not indicate affiliation, model equivalence or approval by any third-party brand owner.
Investment Casting Binders
Compare slurry stability, wetting, shell strength, drying and firing behavior under the buyer's established process.
Catalyst and Washcoat Binders
Evaluate purity, binder interaction, coating adhesion, drying and calcination performance against defined acceptance criteria.
Refractory and Fiber Bonding
Test solids content, penetration, bonding strength, drying response and thermal compatibility in the actual substrate system.
Functional Coatings
Compare formulation stability, film formation, adhesion, surface response and compatibility with other coating ingredients.
Precision Polishing
Qualify particle size, distribution, removal behavior, surface finish and defect performance using the buyer's process.
Custom Industrial Processes
Build a test plan around the current specification, critical process parameters and finished-product acceptance limits.
