RC-65 is a post-emulsifiable high sensitivity fluorescent penetrant designed for inspection of critical parts, turbines blades, assemblies, welds. Type I, method B, C, D, level 3 (according AMS 2644) and level 4 (according ISO 3452-2). Brilliant penetrant for its level of sensitivity. The detection of discontinuities is close to that obtained on Level 4. · The low viscosity of this penetrant ensures a lower consumption of penetrant (on tempered steel), a fast pre-rinse (time saving), and a slow saturation of the emulsifier bath (little penetrant remaining to emulsify after the pre-wash).
