Cabot TS-720 Fumed Silica Procurement Guide: Applications, Dispersion, and Supplier Selection
Cabot® TS-720 is a fumed silica product considered by formulators working with coatings, printing inks, adhesives, and other specialty chemical systems. Buyers searching for a reliable “Cabot TS-720 supplier” are usually looking for more than a competitive price. They also need product traceability, stable quality, flexible order quantities, technical support, and dependable delivery.
This guide explains how to evaluate TS-720 and similar fumed silica products for industrial applications.
What Is Fumed Silica?
Fumed silica is an amorphous, nano-scale silicon dioxide powder produced through a high-temperature process. Its high surface area and surface activity allow it to influence viscosity, thixotropy, suspension stability, and surface appearance.
Depending on the grade and surface treatment, fumed silica may be used for:
Rheology control
Anti-settling performance
Sag resistance
Flow and application control
Surface matting
Scratch and abrasion resistance
Improved storage stability
Different grades are not interchangeable. Buyers should confirm the latest official technical data sheet before selecting a product.
Understanding Cabot® TS-720
Cabot® TS-720, marketed under the Cab-O-Sil® product family, is a product designation associated with treated fumed silica applications. Its exact surface treatment, hydrophobicity, particle characteristics, recommended dosage, and application range must be verified against the current official Cabot TDS and SDS.
In selected solventborne, high-solids, adhesive, ink, and coating systems, treated fumed silica may help improve:
Resistance to sagging
Suspension of pigments and fillers
Thixotropic recovery
Surface appearance
Processing and storage stability
Matte or low-gloss effects, where confirmed by formulation testing
The final result depends on the resin, solvent polarity, pigment and filler loading, dispersion equipment, shear rate, addition sequence, dosage, and curing conditions.
Typical Application Areas
Matte and industrial coatings
Fumed silica may contribute to surface texture, gloss control, viscosity adjustment, and anti-settling performance. Wood coatings, metal coatings, protective coatings, and industrial finishes should be tested separately because the same grade may perform differently in each binder system.
Printing inks
In printing inks, the additive must be evaluated for dispersion quality, viscosity, printability, gloss, transparency, and storage stability.
Adhesives and sealants
Fumed silica can be used to adjust viscosity, improve anti-sag behavior, and help maintain filler suspension. However, compatibility with the adhesive polymer and curing chemistry must be confirmed.
High-solids and solvent-reduced systems
Treated fumed silica is often considered where stronger rheological control is required. Actual performance depends on the formulation and processing method.
Common Procurement Challenges
1. High minimum order quantities
International grades may traditionally be sold in full bags, pallets, or larger commercial quantities. This can create excessive inventory for laboratories and small or medium-sized manufacturers.
A supplier that supports samples or small-batch purchasing can reduce the risk of committing to an unsuitable grade.
2. Product authenticity and storage history
Fumed silica is sensitive to moisture, contamination, packaging damage, and unsuitable storage. Buyers should request:
Original packaging information
Product grade and origin
Batch or lot number
Current TDS and SDS
Certificate of Analysis (COA)
Storage and shelf-life information
Import or distribution documentation where applicable
3. Dispersion and processing difficulties
Poor dispersion may reduce matting efficiency, create agglomerates, increase viscosity unexpectedly, or produce an unstable surface appearance. Selection should therefore include technical discussion about:
4. Fragmented purchasing
Many coating manufacturers purchase resins, pigments, solvents, additives, and rheology modifiers from different suppliers. This can increase freight costs, administrative workload, and delivery risk.

Supply-chain consolidation
According to company information, ERICW serves customers in China and international markets, including Southeast Asia, the Middle East, Africa, North America, and Europe.
The company reports that order consolidation may reduce logistics costs by approximately 15% to 30%, depending on order size, destination, packaging, and freight conditions. Actual savings should be confirmed through a formal quotation.
Technical coordination
ERICW reports that its founding team has more than ten years of specialty chemical experience and has served customers in coatings, inks, adhesives, plastics, and related industries.
The company also reports a strategic collaboration with the Hebei Waterborne Coatings Industrial Technology Research Institute. Technical coordination may include:
Product and grade comparison
Dispersion process discussion
Dosage screening
Compatibility testing
Rheology and gloss evaluation
Selection of related additives
Any technical recommendation should be verified through laboratory and production-scale testing.
How to Select a Fumed Silica Supplier
When evaluating a Cabot TS-720 supplier or an alternative grade, buyers should compare:
Product documentation
Confirm the latest TDS, SDS, COA, batch number, storage conditions, and shelf life.
Product suitability
Check whether the grade is appropriate for the intended resin, solvent system, pigment loading, gloss target, and application method.
Dispersion support
Ask whether the supplier can provide guidance on pre-dispersion, mixing sequence, shear conditions, and dosage screening.
Supply reliability
Compare stock availability, lead time, packaging, minimum order quantity, and emergency replenishment capability.
Total delivered cost
Include product price, freight, handling, packaging, testing, inventory exposure, and possible rework costs.
Recommended Testing Procedure
A practical evaluation can follow four steps:
Laboratory screening: Compare TS-720 with alternative grades at several dosage levels.
Dispersion testing: Evaluate agglomeration, viscosity, fineness, and processing time.
Application testing: Check gloss, matting effect, sag resistance, surface appearance, and printability.
Storage and production validation: Confirm stability during storage and regular manufacturing.
Frequently Asked Questions
Is Cabot TS-720 suitable for every matte coating?
No. Performance depends on the binder, solvent system, pigment loading, dispersion process, and dosage. Testing is required.
Is TS-720 the same as every hydrophobic fumed silica?
No. Surface treatment, particle properties, and technical performance vary by grade and manufacturer.
What documents should be requested?
Buyers should request the latest official TDS, SDS, COA, batch information, storage requirements, and product-origin documents where applicable.
Can a supplier recommend an alternative?
A supplier may suggest alternative grades, but any replacement should be tested for gloss, viscosity, dispersion, storage stability, and final coating performance.
Conclusion
For customers searching for “TS-720 where to buy,” the most reliable approach is to evaluate the complete supplier proposition rather than focus only on price.
Product authenticity, official documentation, small-batch flexibility, dispersion support, supply continuity, and total delivered cost all influence the real value of a fumed silica purchase.
