The use of developers is an important part of the penetrant inspection process. The developer acts to draw the penetrant from the discontinuity and to form a more uniform background increasing the detectability of the penetrant indication. All MET-L-CHEK developers are listed on the Qualified Products List for MIL-I-25135E and AMS-2644. They meet the requirements of ASME Boiler and Pressure Vessel Code and ASTM E-1417 for penetrant inspection materials. They are low in Sulfur, Chlorine and other Halogens, making them safe for use on titanium and high nickel alloys in nuclear applications.
