Where and how a product is used can change significantly over time. Cyanoacrylate (CA) adhesives are a great example.
In 1942, Dr. Harry Coover was working as a chemist for Eastman Chemical Co. when he discovered the cyanoacrylate monomer. Coover created a CA formula and tested it as an extra-clear material for gun sights. Although the formula proved unsuitable for this purpose, Coover noticed that the monomers bonded quickly to various substrates and with incredible strength.
