An aqueous soluble developer for use with post emulsifiable fluorescent penetrants. It forms thin, uniform translucent coatings, which are easily washed off after the inspection. It is supplied as a dry powder which is dissolved in water. Once dissolved, no agitation of the bath is required. 

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.
