Toagosei Co., Ltd. (東亞合成株式会社, Toagosei Kabushiki-gaisha) is a Japanese chemical company, producing cyanoacrylate adhesives since 1963. Other chemical products of the company include high purity gases, soda and chlorine products, and instant glue, which is sold in Japan as Aron Alpha and marketed in the United States as Krazy Glue.
