The samples were lightly sanded before gluing. The samples
were allowed to fully cure for 3 weeks. The standard procedure was used to measure the
strength of the glue. Five samples were tested altogether.

Conclusions / Analysis
The glue appeared to hold very well to the PET plastic.
The mode of failure in all 5 samples appeared to be a very
slow delaminating from the top of the overlap to the bottom.
The sample failed when the delamination reached about half
way down the sample. None of the PET plastic strips failed
during these tests.
While this glue appeared to hold very well to PET, it is
unknown how well this glue would hold in a splice, or with
repeated impacts of the splice with the ground. Follow on
tests are required.
