MR-67

MR-67

MR 67 is a red, fluorescent penetrant that is both water and solvent removable, classified as Type II and Type III. It meets sensitivity level 2 according to EN ISO standards and is suitable for the inspection of surface defects such as cracks and porosity with both white light and UV light. The product has been developed to be environmentally friendly, with reduced solvent content and good degradation properties.


Key features and benefits

  • Removable with either water or solvent, providing flexibility in the cleaning process.

  • Indication in both visible red and fluorescent under UV light, which improves detection in different lighting conditions.

  • Sensitivity level 2 in accordance with EN ISO 3452-2.

  • The carrier medium is water-based in bulk, which reduces odor and makes the product more user-friendly in the field.

  • Environmental properties: produced with minimum solvents, good biodegradability, and ECO-Line without declared hazardous ingredients.


Technical specifications

  • Working temperature range: approx. +5°C to +100°C for the bulk version; aerosols vary more limitedly by model.

  • Storage temperature: approx. +5 °C to +45 °C .

  • Shelf life minimum 3 years under recommended storage.

  • Approvals and standards: EN ISO 3452-2 and EN ISO 3452-5, ASTM E165, RCC-M, ASME Code V Art. 6, as well as other relevant NDT standards.


Areas of application

  • Inspection of welds, castings and metal components for surface defects and porosity.

  • Inspection under both daylight and UV light, where red color and fluorescence provide extra defect visibility.

  • Industrial situations where flexibility is important – both in the choice of removal (water or solvent) and in temperature conditions.

  • For use in production, field inspection and maintenance, especially where environmental considerations are emphasized.
