Abstract
Disclosed are cement compositions for applying to honeycomb bodies. The cement compositions can be applied as a plugging cement composition, segment cement, or even as after applied artificial skins or coatings. The cement compositions generally include an inorganic powder batch mixture consisting essentially of inorganic particles having a particle size greater than 100 nm. The cement compositions can further include an organic binder, a liquid vehicle, and one or more optional processing aids. Also disclosed are honeycomb bodies having the disclosed cement compositions applied thereto and methods for making same.
