A Japanese chemical company and a new name for export.

Krazy Glue is the American name of a Japanese adhesive. Its maker, Toagosei Co., Ltd., is a Tokyo chemical company that English Wikipedia says was founded in 1933 as Yahagi Kogyo by Momosuke Fukuzawa, making ammonium sulphate and acids, and took its present form through a merger with three other chemical companies in 1944. Wikipedia, citing industry reference books, says Toagosei has produced cyanoacrylate adhesives since 1963 and that its instant glue is sold in Japan as Aron Alpha and marketed in the United States as Krazy Glue.

Toagosei America tells the story through a chemist. In a history page on its website, the company says that Kaoru Kimura, a graduate of Kyoto University and a specialist in synthetic organic chemistry, joined Toagosei in the early 1960s while it was researching acrylic acid esters, and that his team developed Aron Alpha in 1963. The adhesive was first used in industry, the company says, and its uses widened into medical and fishing applications.

The consumer version followed. Toagosei America says that by 1971, under Kimura’s guidance, Aron Alpha had been reworked for household use, with attention to the stability of the product and the design of its container, and that it became a popular product in Japan. In 1973, the company says, Toagosei began exporting the adhesive to the United States under a new name: Krazy Glue. The brand’s own website today gives the same year, describing Krazy Glue as introduced to the North American market in 1973 and its original formula as ethyl cyanoacrylate, a glue that sets on contact with moisture on the surfaces being joined. English Wikipedia’s article on Elmer’s Products also dates the North American introduction to 1973.

Borden, Elmer’s, an Ohio plant and Newell.

For much of its American life, Krazy Glue sat alongside a better-known glue brand. English Wikipedia says that in the 1970s Elmer’s, then the adhesives business of the dairy and consumer-products company Borden, began marketing Krazy Glue. Wikipedia, citing Elmer’s own history, adds that in 1989 Borden, Inc. and Toagosei America entered a joint venture to manufacture, sell and distribute cyanoacrylate and anaerobic adhesives under the Krazy Glue and Aron Alpha trademarks.

Production then moved to the United States. Toagosei America’s history page records a groundbreaking ceremony attended by Toagosei and Borden executives in 1993, and the opening of a new Krazy Glue factory in West Jefferson, Ohio, in 1994, with photographs of the plant opening and of the production floor in 1995, where a filling machine is shown loading two-gram tubes. Toagosei America says it began in 1994, is a subsidiary of Toagosei Co., Ltd. in Japan, and makes both its industrial Aron Alpha range and the Krazy Glue product line at the West Jefferson facility.

The marketing partner changed hands more than once. Wikipedia says Kohlberg Kravis Roberts bought Borden in 1994 and set up Elmer’s as a separate operating company, which later merged with the Hunt Corporation, the owner of X-Acto. On 5 October 2015, according to Wikipedia citing The Wall Street Journal, Newell Rubbermaid announced it would acquire Elmer’s Products, described as the maker of Elmer’s glue, Krazy Glue and X-Acto. Our Elmer’s guide covers that side of the story.

The brand’s public face now sits with Toagosei. The terms of service and privacy policy on krazyglue.com, last updated in September 2025, are issued by Toagosei America Inc., and cover krazyglue.com, krazyproducts.com and the Aron Alpha site. The website says Krazy Glue products are manufactured and distributed in the United States and Canada, and groups them into super glues, craft and wood formulas, a Krazy Fix specialty-repair line and Krazy Tape. Toagosei America’s president is Eiichi Okazaki, who the company says joined Toagosei in 1991.

Design and documentation.

Household glue and air-care brands sit on the same kind of shelf, in hardware aisles and supermarket cleaning sections, and both have to be recognised quickly by someone who is usually in the middle of a job. A glue’s identity is often carried by a small tube, a squeeze bottle or a twin syringe, where a name, a colour band and a few words about what the product sticks have to fit on very little space. An air freshener’s identity is carried by a can, a cone, a plug-in or a jar, and by the names given to its scents.

In air care, a fragrance named after a flower, a fruit or a season gives a label designer a colour and a picture to start from. On a glue pack, the name has to share its space with directions for use and safety wording.

Many of these names have also changed owners more than once. Each guide sets out who started the brand, who owns it now and how its packaging and advertising have been described, and marks plainly what rests only on the company’s own word.

A K, a single drop and a man hanging from a beam.

Krazy Glue’s name does much of its identity work. The spelling swaps the C of “crazy” for a K, turning an everyday word into a trade mark that is easy to say, hard to forget and distinct from the generic phrase. English Wikipedia notes that cyanoacrylate glues of this kind are commonly sold as “Crazy Glue” or “Super Glue,” which is part of why the K matters: it is the letter that separates the brand from the category it stands for in conversation.

The brand’s best-known image is a piece of advertising. Krazy Glue’s own website says that for generations the brand was symbolised by “the Hanging Man,” a construction worker whose hard hat was glued to a steel beam by a single drop of Krazy Glue. The company describes the picture as one that “told the whole story: one drop is all it takes.” The image is a demonstration rather than a slogan, built from four elements — a worker, a beam, a hard hat and a drop.

Scale is part of the product story. Toagosei America’s own photographs of its Ohio plant in 1995 show a machine filling two-gram tubes, and the brand’s range today runs from liquids and gels to tapes. Toagosei America’s history also notes that the 1971 consumer version of Aron Alpha in Japan was developed with attention to its container design.

The current website keeps the tone plain and confident, with lines such as “We’re not here to change the world. Just hold it together,” and organises the range by job: all-purpose, craft, wood, home and office, and repair.

For a design guide, Krazy Glue shows how a single misspelled letter and one memorable advertising image can carry a brand for decades, even as its marketing partners change. Compare the Elmer’s and Gorilla Glue guides for two other American glue brands. For this guide we use drop red, steel black, hard-hat yellow and bond white with a condensed sans, an unofficial interpretation; no product or logo is reproduced.
