Abstract

Water washable substantially biodegradable dye penetrant composition for use in non-destructive dye penetrant inspection of parts for locating cracks and flaws therein, consisting essentially of an organic dye, preferably a fluorescent dye, a carrier or solvent for said dye in the form of certain ethoxylated linear alcohols, particularly the biodegradable nonionic surfactants comprised of ethoxylates of a mixture of secondary alcohols having linear alkyl chains of from 11 to 15 carbon atoms, and an average of from 3 to 12 moles of ethylene oxide, and glycol monobutyl ether for thinning the dye penetrant solution substantially without affecting the sensitivity of the penetrant or its biodegradability, and facilitating application of the liquid dye penetrant composition by spraying to the surface of an object or part to be inspected. In the method of application of the dye penetrant composition, such composition is applied to the surface of an object containing cracks and flaws, water is applied to the surface of the object, preferentially removing the glycol monobutyl ether vehicle or carrier, and almost immediately thereafter removing the remaining dye penetrant distributed on the surface, both the removal of the glycol ether component and the remaining dye penetrant occurring in the same washing operation. The part is then inspected under appropriate lighting conditions such as fluorescent or black light, to obtain colored traces from the dye penetrant remaining in the cracks and flaws.
