Fluorescent Post Emulsifiable Penetrant

Post Emulsifiable Penetrants require the careful application of emulsifier to brake-down the penetrant to make it water-washable. These P.E. materials are more costly in material and processing time. Their use is called for by many older specifications especially those concerned with rotating parts of jet engines, possible out of the misconception that they are more sensitive than Water-Washable materials.
