Trishydroxyethyl isocyanurate ( THEIC ) is a chemical compound containing hydroxyl groups . There are three hydroxyethyl radicals on an isocyanurate ring, or more precisely on its nitrogen .

Extraction and presentation

Trishydroxyethyl isocyanurate is produced by adding 3 mol of ethylene oxide to 1 mol of isocyanuric acid.

use

Trishydroxyethyl isocyanurate is used as a monomer in special polyester resins . Compared to conventional monomers for polyester resins, trishydroxyethyl isocyanurate has a special heat resistance due to the isocyanurate ring. Furthermore, resins based on trishydroxyethyl isocyanurate are very resistant to solvents and at the same time very flexible, which makes these resins particularly suitable for use in wire enamels. A disadvantage of trishydroxyethyl isocyanurate is the high price compared to conventional resin monomers.
