ABSTRACT:
An environmentally friendly penetrant used in non-destructive testing of material includes a vegetable oil fatty acid ester. A first embodiment of the penetrant is a post-emulsifiable fluorescent penetrant, a second embodiment of the penetrant is a heatable fluorescent penetrant, a third embodiment of the penetrant is a water washable fluorescent penetrant, a fourth embodiment of the penetrant is a visible water washable penetrant, and a fifth embodiment is a visible solvent removable penetrant. The heatable fluorescent penetrant includes a phenolic antioxidant to provide stability to at least approximately 120 degrees Fahrenheit. A method for using the heatable fluorescent penetrant includes heating the penetrant to lower penetrant viscosity and thus provide better penetration into flaws in the material.
