Developer for dye penetrant testing
In dye penetrant testing, also known as red/white testing, the developer is an indispensable part of the testing process. After application, expiry of the penetration time and intermediate cleaning of the red penetrant the white developer provides the necessary contrast - fine cracks and defects stand out clearly as red indications on a white background.
Developers for dye penetrant testing thus enable a reliable, standard-compliant and visually easily recognizable display - without any UV illumination.

What are developers for dye penetrant testing?
The developer is a white, light-reflecting layer that is applied to the dry test surface after the excess penetrant has been removed. The developer transports the dye penetrant remaining in cracks back to the surface, where it becomes clearly visible. It also forms a strong contrast to the dye penetrant, which further improves evaluability.
This type of penetrant testing is particularly suitable for testing in daylight or wherever no darkening options or UV radiation are available, e.g. using hand lamps.
Advantages of the developer for dye penetrant testing
PFINDER developers are specially formulated for use in combination with our dye penetrants and offer the following advantages:
- Easy evaluation due to red/white contrast formation
- Uniform layer formation on different surfaces
- Fast drying for efficient work steps
- Easy and residue-free removal
- Suitable for metallic and non-metallic materials
- Easy to use as an aerosol spray - if no application technology is available
