Abstract:
A cement mixture for applying to a honeycomb body that includes: (i) inorganic ceramic particles; (ii) an inorganic binder; (iii) an organic binder comprising one or more of a hydrophilic polymer and a hydrophilic additive; and (iv) an aqueous liquid vehicle. The cement mixture exhibits a cement viscosity of less than 7000 Pa·s at a shear rate of less than 0.1/sec and greater than 25 Pa·s at a shear rate from 20/sec to 100/sec.
