Cyanoacrylate (Loctite Super glue - Attak)

Cyanoacrylates were invented in 1942 by Dr. Harry Coover and Fred Joyner of Kodak Laboratories during experiments to make a transparent plastic suitable for gun sights. Although not appropriate for the gun sights, they did find that cyanoacrylates would quickly glue together many materials with great strength. Seeing possibilities for a new adhesive, Kodak developed "Eastman #910" (later "Eastman 910") a few years later as the first true "super glue."



During the 1960s, Eastman Kodak sold cyanoacrylate to Loctite, which in turn repackaged and distributed it under a different brand name "Loctite Quick Set 404." In 1971, Loctite developed its own manufacturing technology and introduced its own line of cyanoacrylate, called Super Bonder. Loctite quickly gained market share and by late 1970s it was believed to have exceeded Eastman Kodak's share in the North American industrial cyanoacrylate market. Other manufacturers of cyanoacrylate included Permabond Division of National Starch and Chemical, Inc., which was a subsidiary of Unilever. Together, Loctite, Eastman and Permabond accounted for approximately 75% of the industrial cyanoacrylate market.
