There are a lot of key differences, so no conclusions should be drawn from this testing. In any case, not all manufacturers report D3330, so we needed to pick one set of conditions and run as many tapes as we had through that one. We hope this testing provides some suggestive information.
And here is a thought: maybe our “benchtop” testing will inspire (or anger?) some experts from PSA tape manufacturers or test programs to conduct some field or field-like service life performance testing. We’d love to see more manufacturers engage in testing along the lines of the Sustainable Building Solutions Test Facility Tremco has going, in partnership with the Department of Energy.
