ABSTRACT:
A method of preparing a fluorescent magnetic composition useful in non-destructing testing of metal work pieces. The method of the invention utilizes a plasticizer in order to effect a more complete encapsulation of fluorescent pigment and magnetic particle powder by film-forming resin. The invention also provides for the composition made by the inventive method, as well as for the method of using the composition in non-destructive testing of magnetizable work pieces.
