Published & Inquiry-Based Materials

Published grades and inquiry-based material families

Published boehmite grades

WBM-P07 fine powder and WBM-S10 NMP-based dispersion are documented standard selections for technical inquiry and evaluation.

Reference SEM for WBM-P07 boehmite powder

WBM-P07 Powder

Maximum formulation flexibility. Select binder, solvent, solids, dispersion process, and rheology locally.

Reference SEM for the WBM-S10 boehmite particle family

WBM-S10 Dispersion

Reduced local dispersion work. Supplied as an NMP-based evaluation dispersion requiring redispersion before use.

Alumina Family

Alumina coating, additive & mesoporous materials

Fine alumina powder grades for separator or electrode coating, ceramic filler evaluation, cathode-additive screening, and high-surface-area mesoporous material studies.

Powder vs. Slurry

Choose the route that fits the trial

Trial objective	Suggested route
Local binder optimization	WBM-P07 powder
International shipment robustness	WBM-P07 powder
Fast FAT setup	WBM-S10 slurry, after formulation and redispersion details are confirmed
Custom solids or rheology window	WBM-P07 powder
Initial coating-line wet trial	WBM-S10 slurry, after compatibility validation
Final edge-coating qualification	Customer-specific validation required

Powder package

Prefer powder when shipment and storage stability, local binder/solvent flexibility, or control of the final rheology and solids window matters most.

NMP-based dispersion

Prefer slurry for faster FAT or process evaluation when a supplied dispersion supports faster setup and the receiving team can follow confirmed formulation, mixing, redispersion, storage, and handling guidance.

Qualification note: Final suitability depends on substrate, coating method, binder and solvent system, drying profile, line conditions, and performance requirements. Process-specific technical discussion can be handled under NDA.

Documentation

U.S.-facing technical and quality support

Available documentation may include Winigen-format TDS, lot-specific COA when available, SDS, storage and handling notes, redispersion guidance, and NDA-supported technical discussion.

Can Winigen support FAT or pilot-line trials?

Yes. Requests can be scoped around coating method, trial quantity, substrate, local mixing capability, drying conditions, and the documentation required for process evaluation.

Is a slurry automatically the easier international-shipping option?

Not always. Powder may offer better storage robustness and more formulation flexibility; slurry can shorten preparation time but requires transport-stability and redispersion planning.
