PROCESS FOR THE PRODUCTION OF POLYISOCYANATES CONTAINING ISOCYANURATE GROUPS FROM ALIPHATIC AND AROMATIC ISOCYANATE COMPOUNDS

摘要

A process for the production of polyisocyanates containing isocyanurate groups by the catalytic trimerization of a mixture of low molecular weight isocyanate components having aliphatically and aromatically bound isocyanate groups in the presence of aminosilyl compounds, the resulting polyisocyanates and their use in coating compositions.
