In 1952 an assistant in Patsy Shermans chemistry
lab at 3M accidentally dropped a beaker full of
a liquid rubber mixture onto the floor, where
it splashed onto Shermans canvas sneakers.
Shermans team had been trying to develop
a new kind of rubber for use in aircraft fuel
lines. But the spilled mixture caught their attention.
Although the mixture didnt change the look
or feel of the canvas, they were unable to wash
it off the shoes. The water and solvents they
used to try to clean the sneakers beaded up and
ran off like water off a ducks back.
Sherman and fellow chemist Sam Smith realized
the mixture could be used to protect fabrics from
water and other fluids. They immediately began
trying to improve it and reduce its cost. After
three years of work, Shermans mixture was
patented and released as Scotchgard Protector.
