epoxy
1. History The invention of epoxy resin has undergone a long period of time. As early as 1891, the German Lindmann hydroquinone and epichlorohydrin with the reaction of condensation into the resin and make use of anhydride curing. But its value has not been revealed. Epoxy plastic has its roots far back in history, to be specific, in 1936, when Dr. Pierre Castan in Switzerland succeeded in synthesizing an epoxy resin that he hardened with pthalic acid anhydride. Dr. Castan's work was licensed by Ciba, Ltd. of Switzerland, which went on to become one of the three major epoxy resin producers worldwide. Ciba's epoxy business was spun off and later sold in the late 1990s and is now the Advanced Materials business unit of Huntsman Corporation of the United States. In 1939, Dr. S.O. Greenlee in the USA developed epoxy resins of epichlorohydrin and bisphenol A example the type of epoxy resins we use today. The purpose of the development of epoxy resins was to find a binding agent for coatings that were resistant to alkali, but it was soon shown that epoxy had significantly more good properties that this. Dr. Greenlee's work was for the firm of Devoe-Reynolds of the United States. Devoe-Reynolds, which was active in the early days of the epoxy resin industry, was sold to Shell Chemical (now Momentive Specialty Chemicals, formerly Hexion, Resolution Polymers and others). Today epoxy has its given place in aerospace, electronics and the automotive industry, as well as in food stuff, pharmaceutical, manufacturing, offshore and the marine industry. Most people are familiar with the word epoxy and associate it with something that is strong. Back in 1960, Nils Malmgren and Curt Augustsson began to formulate and produce products based on epoxy with hardener. In 1967, the scope had become so wide that Nils Malmgren AB was founded, specialized in epoxy-based products. The company was quality certified in 1990 and could strengthen its purposeful quality approach.
