Description
Sherwin RC-65 Penetrant 25L is a post-emulsifiable high-sensitivity fluorescent penetrant designed to inspect critical parts, turbine blades, assemblies, and welds. Type I, method B, C, D, level 3 (according to AMS 2644) and level 4 (according to 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)
Are you in search of a reliable, high-sensitivity fluorescent penetrant for inspecting castings, extrusions, and similar parts? Look no further than Sherwin RC-65 Penetrant 25L. This versatile and trusted solution has been a top choice among aerospace, airframe, turbine engine, and missile manufacturers for over a decade.
Key Features:
- Versatile Application: Sherwin RC-65 Penetrant 25L is suitable for various materials, including aluminium and magnesium, making it a versatile choice for various industries.
- Compliance: This penetrant complies with low sulfur and halogen requirements, ensuring it meets the strictest industry standards.
- High Sensitivity: Sherwin RC-65 Penetrant 25L offers high sensitivity, ensuring it can detect even the most minute flaws in your materials.
- Non-Water Washable: As a non-water washable penetrant, Sherwin RC-65 Penetrant 25L is ideal for applications where water washing is unsuitable.
- Self-Developing: RC-65 is self-developing, often eliminating the need for additional development steps.
- Low Viscosity: Its relatively low viscosity allows for easy application and even coverage.
- Reduced Reliance on Emulsifier: When used with Sherwin Inc’s ER-83A Hydrophilic Emulsifier, most RC-50 can be removed through mechanical scrubbing in the first wash. This reduces the reliance on emulsifiers and ensures that flaw-entrapped penetrants are less likely to be diluted, displaced, or dissolved.
