1. What specific applications is UniPrep® RN 20 suitable for?
UniPrep® RN 20 is suitable for multiple applications, including rinse water and process tank pH adjustment. It is particularly effective in reducing the risk of steel flash rusting when added to rinses, and can be used before or after conversion coating products like Interlox® 5707. It is also appropriate for both spray and immersion applications.
2.What is the optimal pH level for using UniPrep® RN 20 in rinses?
The optimal pH level for using UniPrep® RN 20 in rinses is 8.0, with a range of 7.0-10.0
3. How does UniPrep® RN 20 help reduce flash rusting of steel components?
UniPrep® RN 20 helps reduce the risk of flash rusting of steel components by allowing for the adjustment of pH levels in rinses. When added to rinses, it raises the pH to an optimal level of 8.0, which minimizes the likelihood of flash rusting that can occur with acidic rinses. The product is specifically designed for use in rinse water and process tank pH adjustment, and it can be used before or after conversion coating products. Additionally, continuous dosing of UniPrep® RN 20 can be set up based on production throughput to further minimize the risk of periodic flash rusting, especially when acidic components are introduced.
4. What are the recommended working parameters for temperature when using UniPrep® RN 20?
The recommended working parameters for temperature when using UniPrep® RN 20 are ambient to 50°C
5. What safety precautions should be taken when handling UniPrep® RN 20?
When handling UniPrep® RN 20, the following safety precautions should be taken:
- Avoid direct contact with the material.
- Do not inhale associated mist or vapors.
- Wash contaminated clothing before reuse.
- Refer to the Safety Data Sheet (SDS) for specific precautions before handling this material and for first aid recommendations.
- Keep exposure below the limits recommended by appropriate regional regulatory agencies.

6.UniPrep® RN 20 Solution Control
The solution control for UniPrep® RN 20 is designed to help reduce the risk of flash rusting of steel components before and after conversion coating. The document states that depending on the water source and quality, an acidic rinse can lead to flash rusting of steel components. To minimize this risk, you can use small quantities of UniPrep® RN 20 to adjust the pH to 8.0.
It is noted that UniPrep® RN 20 will be consumed based on production throughput and solution drag out. Continuous dosing can be set up to help minimize the risk of periodic flash rusting. Additionally, the drag-in of acidic components, such as Interlox® 5707, can affect the pH and will require adjustment
