Abstract: Porous ceramic catalyst supports or filters to be provided with catalyst coatings via oxide washcoating processes are pre-coated with polymer barrier layers to prevent washcoat nanoparticle intrusion into the microcracked and/or microporous surfaces of the ceramics, the barrier coatings being formed of hydrocarbon polymers that are soluble or dispersible in polar media, capable of forming neutral or hydrophilic surfaces on porous ceramic supports, and completely vaporizable at moderate washcoat stabilization or catalyst activation temperatures.

Abstract translation: 为了防止修补基面涂层纳米颗粒侵入陶瓷的微裂和/或微孔表面，多孔陶瓷催化剂载体或经过氧化物涂层处理的催化剂涂层被预先涂覆聚合物阻挡层，阻挡涂层由烃聚合物形成， 可溶于或分散于极性介质中，能够在多孔陶瓷载体上形成中性或亲水性表面，并且在适度的洗涂层稳定性或催化剂活化温度下完全可汽化。
