D-76B Water Soluble Dev. 25lbs.

Met-L-Chek D-76B Water Soluble Dev. 25lbs.
The use of a developer is required by most penetrant inspection testing specifications. The developer draws the penetrant from the flaw and creates a uniform surface on which to view the penetrant indication. D-76B is used with fluorescent post-emulsifiable penetrants (Type 1, Methods B & D) as a form ""b"" developer. This form of developer is generally applied by immersion dip, flow on, or gentle airless spray, prior to the drying process. A uniform film will form during the drying.
