Tension and pressure, tears and creeps. The Wingnut Test Facility (WTF) gets dope-slapped in our latest round of experiments.

The Wingnut Test Facility, or WTF, conducting new PSA tape testing in preparation for the NESEA BE14 Demonstration Stages, learned how half a dozen or so tapes are performing on half a dozen different substrates. We also learned, to our surprise, that pressure, or “bellowing,” may not be as important a factor as the wing nuts first thought. (For background on WTF and its prior tape tests, see “Shocking Truth About Tapes Emerges from Wingnut Test Facility!”, and to find GreenSpec listed tapes, see Flexible Flashing.)
Dave Gauthier and I decided two things at the end of our last round of testing:
- We needed a more-realistic, longer-term, “straight-pull” tension test.
- We needed a test that reflected the “bellowing” pressures that tapes see in real installations, driven by wind events.
