The reaction of epichlorohydrin with phenols for form glycidyl ethers was studied by Lindeman in 1891. Fourneau, in 1910 studied the reaction between glycidyl ethers and amines and Schlack, in Germany in 1939 examined glycidyl ethers of Bisphenol A for producing polymers. This was to become the main basis of epoxide resin technology but not until a commercial route to the manufacture of Bisphenol A and epichlorohydrin was developed by Shell, with production commencing in 1955.
The first use of epoxide resins was in 1939 when they were developed for dental use by Castan in Switzerland. Ciba developed them for adhesives in 1945.
During the 1950s epoxide resins were considered alongside polyester resins for making glass fibre reinforced plastics. However, because of the difference in cost between the two types of resin, polyester took over general purpose reinforced plastics and the more expensive epoxide resins were developed for the so-called ‘high tech.’ applications, or ‘advanced composites’ employing reinforcements such as carbon fibres or Kevlar.
