MR Chemie MR 70H Developer White (HOT)

Application Steps 1. Surface Preparation & Cleaning: Remove excess penetrant from the test surface using a lint-free cloth lightly moistened with a remover (such as MR® 91H or MR® 85). Ensure the surface is dry. 2. Temperature Range: Use the spray on components with surface temperatures between +50 °C and +200 °C (+122°F to +392°F). 3. Spraying the Developer: Shake the aerosol can well, then spray MR® 70 H Developer white, system “hot” from a distance of approximately 20 cm. 4. Coating Thickness: Apply a thin, uniform, matte-white layer. Avoid applying too thickly, as a heavy layer will block tiny discontinuities from showing through. 5. Development & Inspection: Allow a development time of 10 to 30 minutes (up to 60 minutes) for the reverse capillary action to draw the penetrant out, revealing clear red or fluorescent indications against the white background
