MR 67 DL Penetrant Red & Fluorescent is a dual indicator penetrant that provides both visible red color and fluorescence under UV light. It is water and solvent removable, classified as Type II/III with sensitivity level 2 according to EN ISO standards. The product uses water as the carrier medium and is an ID for red defects in metal surfaces, with high ease of use and compatibility for many applications.

Key features and benefits

• Water and solvent removable, providing flexibility in the cleaning process.

• Dual indication: Red color under white light / fluorescent under UV, useful in varying inspection environments.

• Sensitivity level 2 according to EN ISO 3452-2, provides good detection of surface defects.

• Suitable for all metals; use on plastic/ceramics should be tested beforehand.

• The carrier medium is water – reducing handling with hazardous solvents and providing more environmentally friendly use.
