FPI Chemicals

Fluorescent Penetrant Inspection (FPI) chemicals are advanced non-destructive testing (NDT) solutions used to detect extremely fine surface defects in non-porous materials. By utilizing fluorescent dyes that glow under ultraviolet (UV) light, FPI enables highly sensitive and accurate detection of cracks, porosity, leaks, and other discontinuities that may not be visible to the naked eye.

These chemicals are widely used in critical industries such as aerospace, automotive, power generation, and manufacturing, where precision and safety are non-negotiable. FPI ensures superior inspection reliability, helping maintain structural integrity and compliance with international quality standards.

Shield Technologies offers a comprehensive range of FPI chemicals including penetrants, developers, removers, and cleaners—formulated for maximum sensitivity, ease of application, and consistent performance across various inspection processes.
