Met-L-Chek FP-93A(M) | Level 2 Fluorescent Post-Emulsifiable Penetrant
Versatile, High-Contrast Inspection for Critical Defects
Met-L-Chek FP-93A(M) is a high-performance, Level 2 (Medium Sensitivity) fluorescent penetrant designed for use in Fluorescent Penetrant Inspection (FPI).It is a Post-Emulsifiable (PE) penetrant, meaning it is formulated to be removed with either a lipophilic or hydrophilic emulsifier for the detection of shallow, wide flaws or deep, tight cracks.
Utilizing advanced dye technology, FP-93A(M) provides a brilliant yellow-green fluorescence under UV-A light ($365$ nm), ensuring maximum contrast against the background and reducing inspector fatigue.
Key Performance Features
Medium Sensitivity (Level 2): Provides the ideal balance for general-purpose inspections, sensitive enough for aerospace fatigue cracks while maintaining low background interference on rougher surfaces.
Multi-Method Versatility: Fully qualified for use with:
Method B: Lipophilic Emulsification
Method C: Solvent Removable (using E-59, E-59A, or R-504)
Method D: Hydrophilic Emulsification
Low Background Noise: Engineered for excellent "washability," ensuring that excess penetrant is removed efficiently without leaching the material out of critical defects.
Non-Corrosive: Safe for use on a wide variety of metals, including aluminum, titanium, magnesium, and high-nickel alloys.
High Flash Point: Formulated for safety in industrial environments with a flash point exceeding $93$°C ($200$°F).
