Title:
POLYISOCYANATE CONTAINING ISOCYANURATE GROUP, METHOD FOR PRODUCING THE SAME AND USE THEREOF
Document Type and Number:
Japanese Patent JP2001323039
Kind Code:
A
Abstract:
To obtain a trimeric isocyanate having a high isocyanate group (NCO) content and an improved low viscosity.
This polyisocyanate containing an isocyanurate group has >80 mass % trimeric content and at least 19.3% NCO content and contains the isocyanurate group obtained from 1,4-diisocyanate-2,2,6-trimethylcyclohexane. The polyisocyanate is preferably hindered by a hindering agent such as ethyl acetoacetate or diisopropylamine. Besides, the polyisocyanate can be produced by reacting the 1,4-diisocyanate-2,2,6-trimethylcyclohexane in the presence of a trimerizing catalyst.
