Abstract
A method for applying washcoat dispersion to catalytic converter support bodies. The temperature of the washcoat dispersion and the temperature of the support body are controlled during the coating process. Preferably, the temperatures are substantially equal. The generally equal temperature results in an equal flow behavior of the washcoat dispersion and therefore results in a generally uniform depth of coating layers. Further, such a small temperature tolerance increases the consistency of the quality of the washcoat coating with regards to mass production of support bodies because the viscosity behavior of the washcoat dispersion is highly predictable.
