RLP-1 Visible & Fluorescent Water Based Penetrant
Met-L-Chek RLP-1 is a water based and dual light response red dye penetrant, 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.
Besides giving a visible red indication under UV-A illumination, RLP-1 produces an orange fluorescence, which improves small flaw detection capability. 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 RLP-1, but each user can tailor the color intensity to their specific needs.
The use of a developer such as D-70, will enhance flaw detection.
