Met-L-Chek E-50 is a Method B (lipophilic) inspection penetrant emulsifier used with VP-31A red visible penetrant.
It is designed to be sprayed onto the post emulsifiable penetrant to render the penetrant water washable. It is a fast acting, so short contact time with the penetrant is required.
E-50 is ideal for use on rough castings and other metal surfaces.
E-50 is listed on the Qualified Products List for AMS-2644E. It meets the requirements of ASME Boiler and Pressure Vessel Code, ASTM E-165 and ASTM E-1417 for penetrant inspection materials.
E-50 is effective in rendering most light oily soils water washable and has been used as a pre-wash cleaner for tough to clean surfaces. It is applied, allowed to soak in for a few minutes and then washed off with water spray.
Low in Sulfar, Chlorine and other halogens.
