ABSTRACT:
A filter for filtering a highly viscous material comprises a filter element including a glass fiber filter medium, preferably resin-bonded, having upstream and downstream sides and a polymeric mesh situated on at least one of the upstream and downstream sides of the filter medium, and preferably on both sides of the filer medium. A non-woven sheet, such as a cellulose paper sheet, may be disposed between the downstream side of the filter medium and the downstream polymeric mesh. The filter element is typically cylindrical and longitudinally pleated to maximize the filtration area in as small a volume as possible. Also provided is a method of filtering a highly viscous material, particularly magnetic coating mixes.
