The product range covers different paper-making and surface-coating directions. Final selection must reflect furnish chemistry, surface charge, binder compatibility, addition point, coating process and final paper requirements.
Choose the Series by Paper Process
Paper grade silica sol should be selected by its role in the mill or coating formulation. Wet-end systems, surface coatings and ink-receptive layers require different charge, particle and compatibility controls.
Inkjet Paper Coating
DM30 provides 30±1% SiO₂, alkaline pH and low published viscosity for compatible ink-receptive coating trials.
Fine Cationic Grades
AP2510 and AP2820 provide 10–30 nm options for cationic paper-making or coating evaluation.
Larger Cationic Grades
APX grades cover 50–120 nm for comparative coating structure and specialty-surface development.
Specialty Modification and Size
PI2020 is organically modified, while P12X provides a 300–600 nm range for specialized paper or film trials.
Data Needed for Paper Grade Recommendation
- Application stage: specify wet end, approach flow, size press, surface treatment, coating or ink-receptive layer.
- Paper specification: identify furnish, recycled content, fillers, basis weight, porosity and surface treatment.
- Chemical system: list starch, binders, retention polymers, sizing agents, pigments and other charged additives.
- Process conditions: provide pH, conductivity, solids, viscosity, mixing order, dosage point and drying conditions.
- Performance targets: define retention, drainage, coating holdout, absorption, drying, printability or anti-blocking requirements.
- Trial controls: include dosage range, control formula, test method, acceptance limits, trial quantity and destination.
Validate Chemistry Before Mill Scale-Up
Charge Compatibility
Check interactions with furnish, pigments, binders and polymers under the actual pH and conductivity.
Laboratory Evaluation
Use handsheets or coating drawdowns to compare process response and paper properties against the control.
Pilot or Machine Trial
Increase dosage stepwise while monitoring runnability, deposits, stability and final paper quality.
Finished Paper Testing
Verify the relevant physical, surface, optical, absorption, printing and converting requirements.

Packaging Options
Available polyethylene packaging sizes are 25 kg, 250 kg and 1000 kg.
Storage Temperature
Store at 0–40°C and prevent freezing. Freezing can cause irreversible gelation.
Direct Sunlight
Avoid prolonged direct sunlight during storage and transportation.
Container Closure
Keep containers closed to reduce evaporation, contamination and silica precipitation.
Paper Grade Silica Sol FAQ
Which paper grade silica-sol models are available?
The published range includes DM30, AP2510, AP2820, APX50-20, APX80-30, APX100-30, PI2020 and P12X.
Which grade is directed toward inkjet paper coating?
DM30 is the published inkjet-paper grade, with 30±1% SiO₂ and a pH range of 9.5–10.5.
What is the difference between AP and PI grades?
The AP and APX grades are inorganic cationic products, while PI2020 is identified as an organically modified cationic grade.
Can one paper grade be used for every paper system?
No. Furnish charge, binders, pigments, process water, dosage point and target paper properties differ, so trials are required.
How should paper grade silica sol be stored?
Store it at 0–40°C, prevent freezing and prolonged sunlight, and keep the package securely closed.

Applications of Paper Grade Silica Sol
The paper grade range supports different wet-end, surface-coating and ink-receptive development directions. Each grade requires validation with the actual furnish, chemicals, coating process and finished-paper specification.
Wet-End Retention Trials
Cationic grades can be screened with compatible polymer programs after furnish chemistry and charge demand are measured.
Drainage and Formation Trials
Laboratory and machine trials can compare drainage, fines retention and sheet formation at controlled dosages.
Paper Surface Coatings
AP, APX and PI grades can be evaluated for coating stability, surface structure and finished-paper properties.
Inkjet Receiving Layers
DM30 can be screened in compatible formulations targeting ink uptake, drying, image density and dot control.
Specialty Paper and Film
P12X and selected larger-particle grades may be assessed for texture, spacing or anti-blocking behavior.
Custom Paper Formulations
Grade and dosage trials can be designed around the buyer's furnish, binder, pigments, process water and test methods.
