Abstract
A method is described for coating a hydrophobic filter membrane so as to render said membrane hydrophilic. This method is particularly for treating polypropylene or polytetrafluoroethylene in which the filter membrane is contemplated to have a pore size not larger than two (2) microns. The treating solution has Triethanolamine Dodecylbenzene Sulfonate (LAS) as the active ingredient. This treatment may use heated air (125.degree. to 200.degree. F.) as a drying assist which renders the membrane to have a substantially instantaneous 'wet-out'.
