IK autopsy

semp-glue

A 40-year-old hypalon IK. I replied an L tear (inset) but then the old rubber coating proved porous so the boat was a write off.
Out if interest, I sawed the boat in half to inspect the I-beam floor and also tried to pull off the hypalon patch I had glued on a few days earlier. The Polymerise glue did not separate. Instead the hypalon coating of the patch (pink, left) stayed glued to the boat and separated from the patch’s nylon core (white, right). Also bits of old orange boat hypalon pilled away. But the glue did not separate.
