Process for manufacturing a modified diisocyanate, a method of manufacturing self-lubricating enameling varnish and manufacturing process of an enameled electric wires.

摘要

A method of manufacturing a modified diisocyanate to which is fixed a pendant chain aliphatic containing at least 15 carbon atoms, obtaining said diisocyanate modified by reaction between an isocyanate functional group of a triisocyanate and a terminal functional group of an aliphatic chain, and carrying out said production of the modified diisocyanate in a solvent, stirred and heated.
