2924 is used as a ceramic coating binder in aqueous slurry systems.
Recommended binder content (solid): ~4 wt% of total solids
The binder is mixed thoroughly with ceramic particles and additives; formulation ratios may be adjusted depending on coating design
Deionized water is used to control slurry viscosity as required
Degassing of the slurry is strongly recommended prior to coating to eliminate air bubbles
The slurry is applied onto the separator surface using standard coating methods (e.g., doctor blade)
Drying is typically performed at ~80 °C under vacuum or ambient conditions
