FLP-1 Fluorescent Water Based Leaker Penetrant Concentrate
Met-L-Chek FLP-1 is a water based fluorescent dye penetrant concentrate, designed for through leak testing and general metal working crack detection. It is a biodegradable penetrant, being free of solvents and oils.
It is low in Sulfur, Chlorine, and other Halogens. It is used on plastics that may be attacked by more traditional inspection penetrants. Being a water based penetrant, it may be diluted with water to fit the inspection needs.
The most common dilutions are 1:1 and 3:1 water to FLP-1, but each user can tailor the fluorescent color intensity to their specific needs.
For through leak testing or to enhance hydrostatic leak detection dilutions of 1000:1, have been used successfully.
The use of a developer such as D-70, will enhance flaw detection.
