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