Hi All,
Received my kit a few weeks ago. Thank you Matt for creating this packraft option. A Jingda iron has arrived and been modified flat.
My educational background is organic chemistry so I am curious about gluing joints. A quick google search shows THF, DMF and DMSO as good solvents for TPU. Of the readily available urethane adhesives, stabond, clifton and HH-66, I have HH-66 in stock. HH-66 uses acetone, MEK and toluene as solvents. Only Clifton uses THF.
First trial, HH-66 shows excellent adhesion. Point of failure was the TPU bond to the fabric not the glue joint.
