Glass Fiber Stress-Corrosion Setup: Selection of a Polymeric Coating Material for the Pushing Rod

Various polymers were tested for leaching of ions via High Resolution Induced Coupled Plasma Mass Spectrometry (HR-ICP-MS) in order to determine which coating materials for the pushing rod are compatible with the glass fiber stress-corrosion setup. The biggest concern is the leaching of Si ions, and is compared among various commercially available polymers - four different polyurethanes, polyvinylchloride, poly(methylmethacrylate) and silicone. Significant amounts of other elements leached were also noted and reported.
