Pierre Castan

from Wikipedia, the free encyclopedia

Pierre Castan (born August 17, 1899 in Bern , † September 12, 1985 in Geneva ) was a Swiss chemist who, along with Paul Schlack, was one of the pioneers in epoxy resins .

Castan received his doctorate from the University of Geneva and was then initially a chemist in the dye industry and at the Swiss Federal Research Institute for Viticulture in Lausanne . From 1928 he developed synthetic resins for dentures at the De Trey AG company in Zurich. In doing so, he developed (without knowing about Schlack's simultaneous development in Germany) epoxy resins (via the reaction of epichlorohydrin with diphenols ), which he applied for a patent in Switzerland in 1938 (granted in 1940). They were useful as a paint and as an adhesive. Castan developed it with several other patents in the 1940s for different applications and in different variants. In 1943, Ciba AG took over the patents and produced a metal adhesive based on them ( Araldit 1946).

In 1950 he went to the Stella AS paint factory in Geneva, where he became technical director. After his retirement in 1970 he was director of the FATIPEC Congress (Federation of Associations of Technicians for Industry of Paints in European Countries) and he was an honorary member of the Swiss Society for Chemical Paints and Dyes. In 1982 he received the Jaubert Prize from the University of Geneva. He died in 1985 after a long illness.
