Summary

This brochure describes an improved Dynamic Drop Test (DDT) setup and procedure applied to clean silicone rubber surfaces under AC conditions.  The work addresses hydrophobicity retention, recovery, and transfer for silicone rubber-based materials. Round Robin Tests (RRT) were used to validate the reproducibility and repeatability of the test results.
