OvivUP™ Final Polishing Ion Exchange Resin

These UPW grade ion exchange resins offer significant improvement in rinse down (to a resistivity ≥ 18.2 MΩ.cm), lower levels of TOC leakage and boron, and significant reduction in the leakage of metallic impurities to the sub-ppt level.

In particular, the non-regenerative mixed-bed resin OvivUP Final Polishing Ion Exchange Resin – M020 premium grade resin demonstrates excellent specificities for obtaining high-quality UPW. OvivUP Final Polishing Ion Exchange Resin – M020 is especially conditioned and rinsed for producing semiconductor grade UPW with the highest quality standards (resistivity ≥ 18.2 MΩ∙cm and TOC ≤ 1 ppb). The premium quality of this resin is achieved by using very high-grade UPW (following IRDS guidelines) for the cleaning and rinsing of the resin during the manufacturing process.

Main features and benefits include:

• Semiconductor grade ion exchange resins
• High purity during manufacturing process
• Peak performances such as superior TOC and resistivity rinse profiles
• Reduced rinse volume, shorter rinsing times
• Low Boron and metal leaks
• Quality assurance with detailed analysis certificate available for each batch of high purity resins
• Gas barrier packaging

The optimum performance from any mixed bed unit can only be achieved if the resin is loaded, commissioned and operated correctly. All equipment must be thoroughly decontaminated using the highest quality ultrapure rinse water to avoid contamination of the resin by either foreign matter or different resin types. Always ensure the resin level conforms to the plant design and always use UPW for the filling, commissioning and rinsing steps. After filling, we recommend mixing the resin with nitrogen (N2) to ensure homogeneous mix of cation and anion resins, which might slightly separate during the filling process.

Resin is delivered from the factory in an ultrapure and clean condition, therefore only a small volume of water is necessary for rinsing during installation. Once the resin packaging is open and the resin is exposed to ambient air conditions, ensure limited exposure time to avoid resin contamination.
