According to the Globe, he founded Industrial Shoe Machinery in Boston in 1954, which he sold to 3M in 1973. Somewhere along the way, he invented the Polygun, the “first industrial glue gun”. 3M manufactured hot glue guns under the name “Polygun” until 2006, when they changed the name to “Scotch-Weld”.
Why is hot glue called hot glue?
As already mentioned, hot glue is applied in a liquid (molten) state after being heated to the adhesive's application temperature. Ensuring the glue is hot enough guarantees a good “wet out” of the first substrate, with glue able to fill small crevices on its surface.
