Urea-formaldehid

Urea-formaldehyde

Urea-formaldehid, juga dikenali sebagai urea-methanal, dinamakan untuk laluan sintesis biasa dan struktur keseluruhannya, adalah resin termoset tanpa telus atau plastik, diperbuat daripada urea dan formaldehid yang dipanaskan dengan kehadiran asas ringan seperti amonia atau piridin . Resin ini digunakan dalam pelekat, kemasan, MDF, dan objek dibentuk. Ia pertama kali disintesis pada 1884 oleh Hölzer, yang bekerja dengan Bernhard Tollens. Pada tahun 1919, Hanns John dari Prague, Czechoslovakia memperoleh paten pertama untuk resin urea-formaldehid.

Urea-formaldehyde, also known as urea-methanal, named so for its common synthesis pathway and overall structure, is a non-transparent thermosetting resin or plastic, made from urea and formaldehyde heated in the presence of a mild base such as ammonia or pyridine. These resins are used in adhesives, finishes, MDF, and molded objects. It was first synthesized in 1884 by Hölzer, who was working with Bernhard Tollens. In 1919, Hanns John of Prague, Czechoslovakia obtained the first patent for urea-formaldehyde resin.
