Description
Ardrox 9PR5 is a colourless, highly volatile, solvent-based penetrant remover. It is fast drying and has a low sulphur and halogen content. Ardrox 9PR5 is mainly used for the removal of both visible red dye and fluorescent penetrants. It can also be used as a solvent pre-cleaner prior to the penetrant application for the removal of oil and greases.
Ardrox 9PR5 Solvent Remover: Enhancing the Precision of Penetrant Testing
Penetrant testing, a crucial component of non-destructive testing (NDT), is widely used to detect surface defects and discontinuities in various industries, ensuring the safety and reliability of critical components. One essential step in the penetrant testing process is the removal of excess penetrant from the surface, where Ardrox 9PR5 solvent remover plays a pivotal role.
Product Description
Ardrox 9PR5 is part of the Ardrox 9PR series, a family of non-chlorinated, volatile solvents specially designed to remove excess penetrant during penetrant testing. These solvents are characterized by their low sulfur and halogen content, making them ideal for NDT applications.
Ardrox 9PR5 is available in bulk material or convenient aerosol cans, providing flexibility in application. Its primary function is twofold: pre-cleaning of surfaces before penetrant application and the removal of excess penetrant after testing.
Physical and Chemical Properties
Ardrox 9PR5 is a clear, colourless liquid with specific properties:
- Density: 0.70 g/ml at 20°C (68°F)
- Flash Point: -4°C (25°F)
Compliance with industry standards ensures its reliability in critical applications:
- EN ISO 3452-2 Method C, class 2
- SAE QPL-AMS 2644 (approval)
- ASME Boiler & Vessel Code Section V, Article 6
These properties make Ardrox 9PR5 an essential component of penetrant testing procedures.
Applications and Use
Pre-Cleaning Solvent:
Before applying penetrant or magnetic ink, Ardrox 9PR5 is sprayed directly onto the surface to be tested. Depending on the level of contamination, the surface may require wiping or flushing with the solvent cleaner. For optimal results, a final wipe-down with a clean cloth or tissue dampened with Ardrox 9PR5 is recommended. This step ensures that the surface is free from oil, grease, and other organic contaminants, laying the foundation for a successful penetrant test.
Excess Penetrant Removal:
After the penetrant has been allowed to dwell on the surface for a specified time, Ardrox 9PR5 comes into play again. Using the wipe-off technique, it is applied to the tested surface. Excess penetrant is removed using a clean, dry, absorbent cloth or paper. Ardrox 9PR5 is then applied to a similar cloth or paper, and the surface is wiped again until a satisfactory background level is achieved. This critical step enhances the visibility of any defects or indications, ensuring accurate test results.
Effects on Materials
When used as prescribed, Ardrox 9PR5 poses minimal risk to commonly used constructional metals, causing no significant corrosion. However, it’s important to note that some rubbers and plastics may experience swelling when exposed to Ardrox 9PR5. Therefore, compatibility testing should be conducted before using it on synthetic surfaces, including painted surfaces.
Storage and Shelf Life
To maintain product integrity, store Ardrox 9PR5 in a cool place, protected from freezing conditions. The shelf life of Ardrox 9PR5 is 36 months.
Labour and Environmental Protection
As with any chemical product, it is essential to adhere to all local and national regulations regarding the transport, storage, use, and waste treatment of Ardrox 9PR5. Safety data sheets should be read and understood before operating the process.
