Loctite

In 1953, American professor Vernon K. Krieble developed anaerobic threadlocking adhesives in his basement laboratory at Trinity College in Hartford, Connecticut. Krieble's company, American Sealants, founded the Loctite brand, which was promoted as ushering in a new era of mechanical reliability by eliminating the vibrational loosening of mechanical fasteners, a frequent cause of machine failure.{{cite web|title=Mechanical Fasteners|url=http://www.henkelna.com/industrial/threadlocking-maintenance-repair-solutions-6131.htm|publisher=Henkel Corporation|accessdate=14 August 2012|archive-date=24 September 2015|archive-url=https://web.archive.org/web/20150924025656/http://www.henkelna.com/industrial/threadlocking-maintenance-repair-solutions-6131.htm|url-status=live}} In 1956, the name Loctite was chosen by Krieble's daughter-in-law, Nancy Brayton Krieble.{{cite news |title=Robert H.

In 1963, American Sealants changed its name to the Loctite Corporation. After Vernon Krieble's death in 1964, his son Robert H. Krieble, also a chemist, served as chief executive until 1985. The Vernon K. Krieble Foundation was established in 1984 in honor of the co-founder.

In 1964, Loctite introduced cyanoacrylate adhesives (a repackaged Eastman product, developed at Tennessee Eastman/Eastman Chemical in 1942, and originally marketed as "Eastman 910"), later known as "Super Glue".{{cite web|title=Super Glue|url=http://www.henkelna.com/cyanoacrylates-ca-adhesives-14976.htm|publisher=Henkel Corporation|accessdate=14 August 2012|archive-date=6 October 2014|archive-url=https://web.archive.org/web/20141006220725/http://www.henkelna.com/cyanoacrylates-ca-adhesives-14976.htm|url-status=live}} It was the first of many new products, including silicones, epoxies, acrylics, and the development of new Loctite anaerobics. The 1980s brought about the addition of a line of micro anaerobic adhesives.{{cite web|title=Anaerobic Adhesives|url=http://www.henkelna.com/anaerobics-adhesives-threadlockers-gaskets-sealants-retaining-14883.htm|publisher=Henkel Corporation|accessdate=14 August 2012|archive-date=28 November 2012|archive-url=https://web.archive.org/web/20121128040520/http://www.henkelna.com/anaerobics-adhesives-threadlockers-gaskets-sealants-retaining-14883.htm|url-status=live}}

In 1997, Loctite was acquired as a flagship brand by Henkel, a German Fortune 500 company.{{Cite news| issn = 0458-3035| last1 = Staff| first1 = Times| last2 = Reports| first2 = Wire| title = Loctite Agrees to Merge With Henkel| work = Los Angeles Times| access-date = 2016-07-11| date = 1996-12-06| url = https://www.latimes.com/archives/la-xpm-1996-12-06-fi-6224-story.html}} Since then, Loctite has remained a primary Henkel brand.{{cite web|title=Loctite History|url=http://www.henkelna.com/cps/rde/xchg/henkel_us/hs.xsl/brands-1556.htm?iname=Loctite%C2%AE&countryCode=us&BU=industrial&parentredDotUID=brands&redDotUID=brands&brand=0000000389¶m1=history|publisher=Henkel Corporation|accessdate=14 August 2012
