NDT Protea P-50 Red Penetrant is a highly sensitive penetrant fluid developed for professional penetrant testing (PT) and non-destructive testing (NDT). P-50 is both water-rinsable and wipeable with detergent, and provides very clear indications when inspecting cracks and surface defects in metal components and welds.

The red penetrant in NDT Protea P-50 penetrates small discontinuities in the material and is then highlighted with a developer such as NDT Protea FK-60 , making even small defects clearly visible under daylight or white light.

P-50 is free from corrosive substances such as sulfur and halogens, and can be used on all metal materials in demanding industrial environments.

Why choose NDT Protea P-50?

✔ Highly sensitive red penetrant
The P-50 provides clear and precise indications of cracks and surface defects.

✔ Water-rinsable and wipe-off formulation
Can be removed with water or cleaning agent such as RC-70 or RC-75.
